However, it is common to experience some light spotting that’s dark brown or light pink during early pregnancy.
Pregnancy with a period: Is it possible?
While some people may experience intermittent vaginal bleeding while they are pregnant, it isn’t possible to have a period. Menstruation only takes place in the absence of pregnancy.
Each month, ovulation occurs when your ovary releases an egg to be fertilized by the sperm. The uterine lining thickens in anticipation of a fertilized egg being implanted, which then results in pregnancy. If an egg isn’t fertilized and implanted, both the egg and the uterine lining are shed through the vagina as menstrual blood.
So, can you have a period while you’re pregnant? The short answer is no. Since you don’t ovulate — or release an egg — during pregnancy, you will not get your monthly period. You'll get your period back either weeks or months after you give birth (how long it takes can depend on whether or not you're breastfeeding) and once you're back in the flow (so to speak!) of your menstrual cycle, you can predict when your next period will arrive with our online period calculator.
How rare is it to be pregnant and have your period?
Despite numerous claims, it isn’t possible to get your period while pregnant. Once the body starts the production of the pregnancy hormone human chorionic gonadotropin (hCG), your periods stop.
I have never felt the need to write a review for any app, but this one deserves recognition. I never used to track my period and I ended up needing to have a blood transfusion because I was bleeding so much for so long. But when I downloaded Flo, It has helped me in so many ways. It has always been accurate, and gives me insight on the symptoms Ive been having on my period, and I can keep my symptoms logged so that I can show my doctor what was going on during my last period. It’s a really useful and helpful app.
Why you might experience a “period” during your first trimester
Though people stop getting their period during pregnancy, it’s possible that they may still experience some bleeding. This bleeding does not necessarily indicate an underlying issue, but it’s important to understand the cause of it — and whether it’s time to see a health care provider.
Bleeding tends to occur more often during the first trimester of pregnancy than the second or third. Estimates suggest that about 25 to 30 percent of pregnant people experience spotting at some point during their first trimester. There are a number of reasons for this bleeding.
Implantation bleeding: This refers to the light spotting that occurs about 10 to 14 days after conception, around the time when your period is due. Many people haven’t yet taken a pregnancy test at this point, so it’s easy to mistake the spotting for a period. This bleeding is lighter than a normal period, however, and only lasts for a couple of days. It occurs due to the implantation of the fertilized egg into the uterine lining.
Cervical changes: Spotting can occur shortly after you get pregnant due to cervical changes, and particularly after having sexual intercourse. As long as no infection is present, there’s no need to be concerned about this.
Other causes: Heavier bleeding that more closely resembles a period during the first trimester of pregnancy can indicate something more serious, including:
- Ectopic pregnancy
- Molar pregnancy
- Subchorionic hemorrhage, also known as subchorionic hematoma (bleeding between the placenta and the wall of the uterus)
- Gestational trophoblast disease (GTD), a rare group of tumors that grow from the cells that normally develop into the placenta
These are all medical emergencies, and it’s important to see a health care professional immediately. They are often accompanied by symptoms other than bleeding, including:
- Back pain
- Severe abdominal pain or cramps
- Loss of consciousness or faintness
- Shoulder pain
- Changes in vaginal discharge
- Uncontrollable vomiting and nausea
Bleeding later in pregnancy: why it happens
We’ve already discussed why it isn’t possible to have a period during pregnancy, and why some people may experience light bleeding or spotting during their first trimester. Bleeding during the second and third trimesters is possible, though not common, and it may be an indicator that something else is going on. If you experience bleeding later in your pregnancy, it’s important to see your health care provider.
Potential reasons for mid- or late-term pregnancy bleeding include:
- Sexual intercourse: Having sex during mid- and late pregnancy can cause some spotting or light bleeding due to increased sensitivity of the cervical and vaginal tissues during this time.
- Preterm or term labor: This refers to delivery of the baby before 37 weeks of pregnancy. Cervical dilatation and uterine contractions generally occur to help the fetus move down, which can result in bleeding and a large amount of vaginal discharge. Other symptoms include a backache, abdominal cramping, changes in vaginal discharge, and a sensation of vaginal pressure.
- Placenta previa: In this condition, the placenta is located close to or over the cervical opening. There are no symptoms other than vaginal bleeding, and it may hinder labor and delivery.
- Placental abruption: This is a medical emergency that occurs during late pregnancy when the placenta starts separating from the uterine lining before the birth of the baby. It can cause heavy vaginal bleeding, as well as severe cramping and stomach pain. Certain health issues, like hypertension, may increase your risk of developing placental abruption.
- Uterine rupture: This occurs when the uterine muscles tear or separate before or during labor. It’s considered a medical emergency, as it may result in uncontrolled vaginal bleeding. Though rare, the condition most often occurs in people who have a history of uterine surgery or cesarean delivery.
When to see your health care provider
Because it isn’t possible to get your period while pregnant, it’s important to be mindful of any bleeding you do experience during this time. While light bleeding or spotting during the first trimester is usually normal, bleeding that is accompanied by other symptoms may indicate something more serious, and it’s important to see a health care provider immediately. These symptoms include:
- Cramping and pain
- Fainting or dizziness
- Passing clots or heavy bleeding
- Severe pain in your pelvis and stomach
It’s important to visit your health care provider if your bleeding is bright red in color and is heavy enough to soak through a pad. Pelvic pain and vaginal bleeding in the early stages of pregnancy may indicate an ectopic pregnancy. If you suspect this, see your health care provider as soon as possible.
There’s a lot of discussion surrounding pregnancy and periods, and we want to clear things up. Can you have a period and be pregnant? No. Since your period stops after your body starts producing hCG — also known as the pregnancy hormone — it isn’t possible to experience a true period during pregnancy.
During the early stages of pregnancy, however, some people experience spotting or light bleeding — and it’s usually normal. This bleeding is called implantation bleeding, and it happens when the fertilized egg implants in the uterine lining.
First trimester bleeding that occurs alongside other symptoms (like dizziness or pain) may indicate a more serious issue, such as ectopic pregnancy, infection, miscarriage, molar pregnancy, subchorionic hemorrhage, or cervical changes. If you are concerned and suspect an underlying cause for the bleeding, it’s important to seek immediate medical attention — many of these conditions are medical emergencies.
It’s also possible to bleed during the middle and late stages of pregnancy. This bleeding is less common and may indicate a medical emergency such as preterm or term labor, placenta previa, placental abruption, or uterine rupture. Having sexual intercourse during the later stages can also cause bleeding, though it’s usually quite light.
If you experience bleeding as well as symptoms like cramping, pain, fainting or dizziness, passing clots or heavy bleeding, and severe pain in your pelvis and stomach, be sure to see your health care provider right away.
