Can You Be Pregnant and Still Have Your Period?

  • Menstruation is a sure sign that you are not pregnant.
  • Not every kind of vaginal bleeding is menstrual.
  • Some forms of period-like bleeding (such as implantation bleeding) can be signs of pregnancy.

Can You Get Your Period If You Are Pregnant?

The short answer is: No. If you are really on your period, you cannot be pregnant — BUT it is possible to experience menstrual-like bleeding during pregnancy.

Any vaginal bleeding other than menstrual bleeding is often referred to as breakthrough or intermenstrual bleeding. It is usually weaker than menstrual bleeding (many women describe it as "spotting"). It often ceases after only one day.

ℹ️ Pregnant and bleeding: Approximately one in five women experience spotting in early pregnancy. This is definitely not a menstrual period since pregnancy and menstrual bleeding are mutually exclusive.

Short, Very Early, or Light Period — A Sign of Pregnancy?

If your period came sooner than usual (perhaps three, four, or multiple days earlier), lasted only a few days, or wasn’t as strong, this does not necessarily mean that you are pregnant. Even women with relatively regular cycles may experience shifts in timing or intensity. Some women have lighter periods than others.

Nevertheless, it may be that the bleeding was not your menstruation but breakthrough bleeding. Consult your doctor if you are concerned about other symptoms that could point toward a pregnancy.

Possible Causes of Vaginal Bleeding During Pregnancy

Vaginal bleeding, also known as breakthrough bleeding, at the beginning of pregnancy can have many causes. Although usually harmless, it is reason enough to consult a doctor. The amount of blood alone is not a sufficient indicator of the seriousness of the situation.

Other possible causes of bleeding could be life-threatening to the mother or baby. Therefore, any presence of blood should be taken seriously and brought to your doctor’s attention immediately.

Difference Between Period and Spotting

How do you identify the difference between menstrual bleeding and breakthrough bleeding or spotting?

Preparation by Progesterone

After the egg cell is released into the fallopian tube (ovulation), the female body assumes that the egg will be fertilized and a new life is about to begin. Progesterone, a hormone that enables the body to accommodate the fertilized egg perfectly, is produced in preparation. This leads to the thickening of the uterine lining.

The Uterine Lining is Expelled through Bleeding

If no fertilized egg implants in the uterus within the following days, progesterone levels decrease. Since no new life has been created, the nutrients contained within the endometrium are not needed. Consequently, the endometrium, the lining of the uterus, is excreted in the form of blood and small pieces of tissue.

Menstrual bleeding is usually heavier than any breakthrough bleeding.

If you are really on your period, you cannot be pregnant.

Unlike menstrual bleeding, spotting is usually due to hormonal fluctuations.

This intermenstrual bleeding can even occur during your fertile window and may cover up other signs of fertility (such as increased cervical mucus).

It is possible to become pregnant during this time!

Ovulation Bleeding

Ovulation can cause spotting. This light bleeding in the middle of one’s cycle is known as ovulation bleeding. It is caused by a shift in hormone levels during ovulation.

Why Pregnancy and Period Are Mutually Exclusive:

If the egg is fertilized, it implants in the uterus about six days later. At this point, the body starts producing the pregnancy hormone, human chorionic gonadotropin (hCG). This is what is detected by a home pregnancy test. HGC ensures that progesterone continues to perform its tasks diligently over the next nine months.

The lining of the uterus, already prepared before implantation, continues to thicken. Simultaneously, the placenta, responsible for the baby’s nourishment and protection, starts to develop. At the same time, the cervix is sealed by a plug of mucus.

Rather than cleaning out the “biological hotel room,” as during menstruation, it is now newly furnished. Therefore, a pregnant woman cannot have a period.

..."Today, I am still spotting, but without pain. It is starting to feel and look like a regular period; it is just as strong now..."

"12/27 (Tuesday) was the last time I had sex (on the pill). On Wednesday, I had to take antibiotics. My 'period'(?) started on Friday. The bleeding was on the light side. The next month my 'period'(?) was so light, it could have been spotting... It lasted the full six days, and the color of my blood was sometimes red and sometimes brown... but it was a lot lighter than usual."...

..."My period has been super regular for years — ALWAYS on the 10th. No changes. My period started today. It was very different from my normal period: very light, reddish-brown, and no pain...

...Could this spotting be implantation bleeding? Has anyone else had this experience?"...
