After a girl is pregnant, she no longer gets her period. But girls who are pregnant can have other bleeding that might look like a period. For example, there can be a small amount of bleeding when a fertilized egg implants in the uterus. However, they may still begin to ovulate again soon after giving birth.
Therefore, doctors may recommend some form of birth control while a woman is breast-feeding if she does not wish to get pregnant. The menstrual cycle occurs to facilitate pregnancy. Ovulation , when the ovary releases an egg, occurs midway through the cycle. An egg is only viable for about 12—24 hours after a woman ovulates. If sperm cells are present and able to fertilize the egg, the egg will implant itself in the uterus, resulting in pregnancy. If there is no fertilization, menstruation will occur, and the body will shed the uterine lining so that it can begin making a new one for the next cycle.
Although a woman will not have a period when she is pregnant, she may still experience some bleeding. While bleeding is not necessarily a sign of an underlying problem, it is essential to understand the potential causes and know when to speak to a doctor. Bleeding tends to be more common during the first trimester. Some mild spotting can occur as the placenta implants in the uterus. A woman can also experience changes in the cervical cells during pregnancy, which may cause some light bleeding, especially after having sex.
If a woman does experience bleeding at any stage of pregnancy and is concerned, she should note the color, amount, and consistency of the bleeding and speak to a doctor. Join now to personalize. Photo credit: iStock. You can't have your menstrual period while you're pregnant.

A true period is blood loss that occurs at the end of a menstrual cycle as a result of your egg not being fertilized by sperm.
When an egg goes unfertilized, hormones—the ones that control the release of the egg into your fallopian tubes and cause your womb lining to thicken—drop in levels at the end of the month. Your womb lining then disintegrates and is shed in what we commonly refer to as a period. If you're pregnant, an egg has already been fertilized and is growing as an embryo within the walls of your uterus.
Since your womb lining is not being discarded at the end of each month, you no longer have a period. This is why one of the early signs of pregnancy is a missed period.
