Missed Period

Historically, the first sign of pregnancy has been considered a missed period.  A delayed or missed period is often the trigger that leads someone to suspect or to test for pregnancy.

What causes a missed period during pregnancy?

A missed period or menstrual cycle is triggered by the pregnancy related hormones released by the placenta informing your body that it is pregnant.

When does a missed period occur?

A missed period is expected during the first month of pregnancy.  However, it is possible to be pregnant and to have a period, but this period is usually lighter, shorter or spottier.  The belief is that this is not actually a period but rather heavier implantation bleeding. 

Some women have actually experienced cyclical bleeding during their pregnancy, but this is rare and not expected.  Most women that do experience a period although pregnant, cease to have a period by the second or third month.

Bleeding is always a symptom that needs to be examined by your health care provider.  Although early bleeding is common

How frequently does a missed period occur?

Although a missed period is expected with each pregnancy; approximately 40% of women experience bleeding during their first month.  Less than half of these result in a miscarriage, but you are still advised to contact your health care provider.
