Symptoms of Pregnancy

In most cases vaginal bleeding is actually implantation bleeding that occurs from the fertilized egg implanting in the uterine wall.  Bleeding during pregnancy is actually common during pregnancy.

What causes bleeding during pregnancy?

Bleeding may be causes by the fertilized egg implanting in the uterine wall or unexplained breakthrough bleeding.  It may also be caused by a complication related to your pregnancy.  Although it is possible to bleed and have nothing wrong, bleeding is a symptom of pregnancy that is always accompanied by the recommendation to contact your health care provider.

When does bleeding occur during pregnancy?

Bleeding is most common during the first 12 weeks of pregnancy.  If it is actually implantation bleeding it probably occurred within the first week after conception.  Bleeding may occur at any time during pregnancy, but the later in the pregnancy it occurs the more important it is to contact your health care provider.

How frequently do they occur?

About 40% of women will experience bleeding during their pregnancy; however less than half of these will have a miscarriage.  Even though it is in your favor of probably having a normal pregnancy, contact your healthcare provider if you are bleeding during your pregnancy.
