If you're in your first trimester of pregnancy and you're experience vaginal bleeding…take a breath. There can be a number of reasons for first trimester bleeding. I know that any type of bleeding while pregnant can be alarming, even for the most pragmatic mom-to-be. But I'm hear to give you the facts to hopefully give you better insight into your pregnancy.
First trimester bleeding is just one of the things about the first trimester than can make this trimester more difficult than the others. Vaginal bleeding during pregnancy is never comfortable to experience, but in the first trimester it can be especially daunting for new mothers who fear that their pregnancies may not have the outcome that they hope and pray for.
There is good news. You are not alone. Spotting or light bleeding in the first trimester occurs in about 25% of all pregnancies and often turns out to be harmless.
First Trimester Bleeding
Although it may be unnerving, vaginal bleeding in the first trimester might actually be more common than you think. Since nearly one third of all pregnancies experience some sort of bleeding in early pregnancy, you can rest assured that your body is not the only one handling early pregnancy this way.
I have experienced first trimester bleeding with all three of my pregnancies so I know how difficult it can be to not know what to expect.During my pregnancies, every little sign or symptom that sparks fear in me inspires an intense amount of research on my part. Lucky you, I have done my fair share of learning about causes of bleeding during pregnancy, how to know when it's serious, and what I can do about it. Plus, it doesn't hurt that I am a Labor & Delivery nurse. This is my world!
In this post, I've laid it all out there for you so that you can hopefully rest your mind a little quicker than I could when I was having first trimester bleeding. Keep reading to learn everything you need to know about bleeding in early pregnancy.
Does Bleeding During Pregnancy Mean Miscarriage?
I know that it is scary and you feel worried about your pregnancy, but first trimester bleeding does not always mean miscarriage. In fact, 15-20% of women with normal, healthy pregnancies will have first trimester bleeding. On top of that, if a heartbeat is seen on ultrasound, over 90% of women who experience first trimester vaginal bleeding will not miscarry. To me, this is comforting to hear.
Even so, when you have bleeding in your first trimester, you now technically are experiencing a “threatened miscarriage”. This is because the threat of miscarriage does increase slightly when you have first-trimester bleeding.
Your provider will diagnose you with “threatened miscarriage” if you are having bleeding and/or mild cramping but the cervix has remained closed and the embryo is still viable. In many cases of threatened miscarriage, the bleeding stops and the pregnancy continues to be normal and healthy. For others, the bleeding increases and eventually results in a spontaneous pregnancy loss.
Spotting vs. Bleeding During Pregnancy
Although any bleeding before 20 weeks gestation is a “threatened miscarriage” by definition, the type of bleeding that you have matters significantly.
Light bleeding, or spotting is common in the first trimester of pregnancy and is typically no cause for alarm. You will know that you are experiencing “spotting” as apposed to “bleeding” if the discharge of blood is just a few drops occasionally found on your underwear or on the tissue paper after you wipe. If there isn't enough blood at any one time to cover a panty liner, then you are experiencing “spotting”. Spotting is usually not bright red in color but instead pink or brown.
Bleeding, on the other hand, is when you have a heavier flow of blood. In order to not saturate your clothes with blood, you will need to wear a pad. This blood is typically bright or dark red in color, similar to what you find during a period.
Causes of Bleeding During Pregnancy
1. Implantation Spotting
Implantation bleeding is one of the earliest signs of pregnancy. This type of early pregnancy bleeding happens before any signs of nausea, breast changes, or a positive pregnancy test and is just that – a symptom of pregnancy. Implantation bleeding is harmless and not a threat to your pregnancy.
This type of bleeding happens when the fertilized egg attaches itself to the uterine lining. The damage that the embryo does to the lining as it buries deeper can cause a few days of light bleeding or spotting.
Some women experience this spotting within the first six to twelve days after ovulation before she even knows she is pregnant or misses her period. Some women actually can confuse this spotting for a very light period because it comes just before the time when a period is expected to start.
Implantation bleeding can be really confusing for many women because the amount, consistency, color, and duration of the bleeding can be different for everyone. Typical implantation bleeding for most women is light spotting for a couple of days not resembling the amount or duration of a period. Implantation bleeding should be pink or brown without the presence of bright red blood.

2. Subchorionic Hemorrhage
Also called a Subchorionic Hematoma, this is a clot or build up of blood behind the placenta, threatening miscarriage of your pregnancy. Thankfully, the diagnosis of a Subchorionic Hemorrhage in early pregnancy does not indicate an imminent miscarriage. A Subchorionic hemorrhage can resolve and result in an uncomplicated pregnancy.
If a Subchorionic Hemorrhage is present but there are fetal heart sounds, likely you will be cautioned that you can expect continued bleeding without miscarriage OR a possible impending miscarriage. There is no way to know if your body will reabsorb the hemorrhage or if the hemorrhage will grow large enough to detach the placenta from the wall of the uterus and result in a miscarriage.
Don't worry too much. It is absolutely possible to continue with a normal pregnancy after finding out that you have a Subchorionic Hemorrhage. Most Subchorionic hemorrhages resolve on their own and do not need intervention of any kind.
3. Cervical Changes
In early pregnancy, your cervix is receiving more blood flow than prior to getting pregnant. Anything that might irritate the cervix such as a cervical exam, Pap smear, or intercourse can all cause bleeding from the cervix.
Sometimes your cervix will become quite friable in pregnancy and every little thing will cause irritation of the cervix and create small amounts of bleeding during pregnancy. This type of bleeding has no threat to your pregnancy and will typically resolve by the end of the first trimester when your body starts to get used to all of the changes it's going through.
Any physical action that may result in the cervix being disturbed can be considered trauma. Even normal, seemingly harmless actions such as sexual intercourse, a gynecological exam, a vaginal ultrasound, or even heavy lifting/ exercise can cause bleeding in early pregnancy.
Spotting may occur within 24 hours after intercourse, a cervical exam done by your provider, or Pap smear. If the bleeding continues longer than 24-48 hours after cervical trauma, you can assume that there is another underlying problem.
Any infection in the vagina such as bacterial vaginosis or a sexually transmitted infection such as chlamydia, gonorrhea, or herpes, can cause bleeding in the first trimester. In this case, the infection needs to be treated as soon as possible in order for the bleeding to subside.
6. Ectopic Pregnancy (Tubal Pregnancy)
In an ectopic pregnancy, the fertilized egg implants outside of the uterus, typically in the fallopian tube. If the embryo continues to grow, it can cause damage to the Fallopian tube and even cause it to burst. This type of pregnancy will not be able to progress normally and can be life threatening to the mother if left untreated.
Symptoms of an ectopic pregnancy include bleeding, cramping, and sharp abdominal pain. An ectopic pregnancy might be considered if the Beta HCG level is higher than 1,500 to 2,000 mIU per mL but the gestational sac is not visible upon ultrasound.
7. Gestational Trophoblastic Disease
Also known as a Molar Pregnancy, this rare type of pregnancy is when abnormal tissue grows in place of a baby. This type of pregnancy will not result in a viable baby and must be treated with a D&C. If untreated, a molar pregnancy can become cancerous and spread to other parts of the body.
A molar pregnancy occurs when there is an abnormality during fertilization that results in the growth of abnormal tissue. Although the embryo is not typical of a healthy pregnancy, it will lead to the typical symptoms of early pregnancy until the mole has been diagnosed. A molar pregnancy is considered when an unexpectedly high beta HCG level is noted and then ultrasound is performed to confirm the diagnosis.
8. Incomplete Miscarriage
Typically a miscarriage is referred to by medical professionals as a “Spontaneous Abortion” meaning that it happened on it's own. If you are experiencing an incomplete miscarriage, the embryo does not have a heartbeat past 6 weeks of gestation but your body has not passed the pregnancy. Sometimes with an incomplete miscarriage, you will experience bright red spotting or bleeding but your uterus has not been triggered to expel the pregnancy and may need medical assistance to do so.
Sadly, miscarriages happen in around 15-20 percent of all pregnancies. Miscarriage is most common in the first 12 weeks of pregnancy but is defined as the spontaneous loss of a pregnancy in the first 20 weeks. A miscarriage often presents itself with bright red bleeding, similar to a period with cramping, abdominal pain, and/or back pain. Upon exam by your provider, your cervix will be open and tissue may pass through the vagina.
If you are very early, you may be experiencing a chemical pregnancy. A chemical pregnancy is a type of miscarriage that you will only be aware of if you had a very early positive pregnancy test. A chemical pregnancy occurs when an egg is fertilized but never fully implants into the uterus. You may be able to get a positive pregnancy test very early on but then have vaginal bleeding and cramping immediately afterwards as the fertilized ovum fails to implant.

10. Non-Obstetric causes of bleeding
Non-obstetric meaning not pregnancy related. These causes can be cervicitis, vaginitis, cystitis, cervical cancer, or polyps. Polyps are harmless growths on the cervix that are more likely to bleed during pregnancy because of your body's higher estrogen levels and higher blood volume during that time. Cervicitis and vaginitis are just basically irritation of the cervix or vagina. This can happen more often in pregnancy than otherwise but typically does not pose risk to your pregnancy.
Yes, this one is surprising, I'll admit. Hemorrhoids are a non-vaginal cause of bleeding in early pregnancy but it can often be mistaken for vaginal bleeding. If you are finding blood on the toilet paper after wiping or blood in the toilet after using the restroom, you may be confusing blood from the rectum as blood from the vagina.
Bright red blood from the rectum can be caused by hemorrhoids, a rectal polyp, or a tear in the rectum caused by constipation. Rectal bleeding is not a cause for alarm regarding the safety of your pregnancy, but it may be uncomfortable. Talk to your doctor about what you are experiencing to see if there is anything that can be done.
Does First Trimester Bleeding Always Indicate a Problem?
Bleeding during early pregnancy is not necessarily expected and may be abnormal depending on the source of bleeding, but it is not always a cause for concern. Don't panic when you find yourself experiencing light bleeding in the first trimester.
Most pregnancies, even those with first trimester bleeding, will end up progressing normally. If you are far enough along to detect a heartbeat, you are already farther along than the vast majority of all miscarriages. If your baby's heartbeat has been seen and heard by you and your provider, you can have a little bit more reassurance that your pregnancy is on the right track-even with your first trimester bleeding.
The urgency at which you get medical care depends on what kind of bleeding you are having and what other symptoms you have along with it. Implantation bleeding, sexual intercourse, hemorrhoids, or cervical changes in early pregnancy do not indicate a problem with the viability of your pregnancy. Still, no matter what kind of bleeding you are experiencing, whether it be spotting or something more, you should always communicate your symptoms with your OB provider to be sure it is not something serious. This is especially important if you are having heavy bleeding similar to your menstrual period or severe abdominal cramping to rule out serious complications such as ectopic pregnancy.
Normal First Trimester Bleeding
Often times, when a woman experiences early pregnancy bleeding she will be able to find signs that let her know that her bleeding isn't something to lose sleep over.
As we have previously discussed, there are times when first trimester bleeding is perfectly normal and expected to be harmless.
- Implantation bleeding
- Cervical changes
- Sexual Intercourse
- Cervical Polyps
Since it is difficult to tell the difference between “normal” and serious bleeding during pregnancy, it is best to talk to your doctor about what you're experiencing to be sure that it's not dangerous.
When To Worry About First Trimester Bleeding
Although first trimester bleeding is not always an emergency, there are certainly times that bleeding during pregnancy can be serious and require a visit with your doctor. In order to know when spotting or bleeding during pregnancy is serious, you need to be constantly aware of the signs that may indicate a pregnancy complication.
Things that you need to remember to keep track of when experiencing bleeding during pregnancy are whether it is heavy or light, how long it lasts, when it occurs, if it is triggered by something, what color it is, and the consistency. Is it mild spotting or a flow like a period? Has it been a few times over the last couple of days or has it been progressing over time? Do you only see it after sex and exercise or does it happen after rest? Is it light pink, bright red, or brownish? Is it thin, creamy, chunky, or slippery?
Seek immediate medical attention if you are experiencing any of the following symptoms, which could be signs of serious problems related to miscarriage:
- Severe pain in the lower abdomen
- Heavy bleeding, like the heaviest day of your period
- Bleeding along side moderate to severe cramping
- Passing fetal tissue through the vagina
- A fever of 100.4 degrees Fahrenheit or more
- Dizziness or fainting
Is It Implantation Bleeding or an Early Miscarriage?
If you have already found out that you are pregnant, any bleeding at all will reasonably make you question what is going on. Is it implantation bleeding? Is it a very early miscarriage? What do I do? It can all be very confusing.
I'll try to clear things up a little bit more.
If you are worried that miscarriage may be imminent, speak to your doctor about possibly running a Beta HCG level. This will consist of at least two blood draws 48 to 72 hours apart. This test helps to determine if your human chorionic gonadotropin (the hormone produced by the embryo's placenta) is approximately doubling in an appropriate time frame. If your HCG level is approximately doubling in 48-72 hours, then you can be temporarily reassured that miscarriage is not upon you.
If you are in the group of women who experience bleeding with implantation, there is nothing to worry about. It's totally normal. If your bleeding is not due to an impending miscarriage and is in fact just implantation bleeding, it will not have clots, fill a pad, happen in conjunction with period-like cramping, or get progressively heavier as time goes on.
Managing First Trimester Bleeding
Many times, all you need is a little bit of reassurance. I know how it feels to want someone to just tell you “it's going to be ok. This is totally normal”. Most of the time you won't get this from your provider because they can't guarantee that everything is going to be “ok”. You are the only one that will be able to give yourself that reassurance. Your first step in managing first trimester bleeding is to get educated about it.
The second thing you need to do to manage your first trimester bleeding is to give yourself time. There is no use in googling “how to stop first trimester bleeding” or “what can I do to prevent first trimester bleeding”. This assumes that you have full control over what's happening within your body and that if you're bleeding, then you are doing something wrong. This is just not the case.
The third thing to do to manage your first trimester bleeding is to never use a tampon or have sex while you are currently experiencing bleeding or spotting. If you are having any type of bleeding during pregnancy, you should wear a pad or panty liner. Wearing a pad will help you keep track of how much blood you're having, what color it is, and help you communicate effectively with your provider if you need to.
Treatment of First Trimester Bleeding
If your bleeding is due to miscarriage in early pregnancy, there is nothing that can be done to stop it. Unless the cause of first trimester bleeding is a risk to your own life, there is likely nothing to be done. Usually, if the bleeding is diagnosed as implantation bleeding, Subchorionic Hemorrhage, trauma, or cervical changes, there will be no other intervention other than resting and waiting.
Sadly, if your bleeding has been determined to be something more concerning such as molar pregnancy, ectopic pregnancy, incomplete miscarriage or imminent miscarriage, the only option (other than waiting it out – which can sometimes be a very bad idea) is intervention to help end/remove the pregnancy. We cannot stop an imminent miscarriage and cannot reverse a poor pregnancy outcome. I really wish we could.
In cases where there is no other fate but the end of the pregnancy, the intervention that you can anticipate will be surgery to remove the embryo, medication to help expel the embryo, or, yet again, time to wait until it all passes on it's own.
What You Can Do About First Trimester Bleeding
Although you may not be able to stop the spotting or bleeding that you experience during early pregnancy, there are things that you can do to nurture your pregnancy during a time when you are wondering if your pregnancy will end with everything you ever wanted or your worst nightmare. Talk to your provider and try to do these few things:
- Get rest. Try to kick your feet up, take more naps, and give yourself more opportunity to relax. Your body is doing a lot of work right now. It might just need you to slow down a little to allow it to do this huge and important job.
- Hydrate. I feel like drinking more water is the key to a healthy pregnancy for so many reasons. Water, water, water. Make a point to drink more.
- Do not over-exert yourself. It is a good idea to exercise in pregnancy to keep your body healthy but try to modify as much as possible to accommodate your pregnancy. Limit heavy lifting, running, jumping, and other strenuous activities.
Remember that bleeding in pregnancy and miscarriage are not your fault. There is nothing that you did wrong, nothing that you could have done differently, and nothing to feel guilty about. Do your best to treat your body and mind well during your pregnancy and know that that is all you can do.
Bleeding In The First Trimester
While it is completely natural to worry about miscarriage if you are having first trimester bleeding, you can see from this post that there are a number of other reasons why you can be experiencing spotting during your pregnancy. Some reasons are harmless, some reasons just take time, and others are more serious. The best thing that you can do is breathe, say a prayer, and talk to your doctor so that together you can identify the cause of your first trimester bleeding and make a plan.
