Why do some women have a period while pregnant?

Hey PHS

It is possible and common for women to experience “period like” bleeding when pregnant. However, when hCG is released into the body it “tells” the ovaries to release progesterone which prevents menstruation. In fact, a very big reason many women do not realize they are pregnant until many weeks later is because they believe they are having a period when in fact it is really not a period.

But saying that some women get this bleeding every month when there period should be due throughout pregnancy.

Hi, when I was pg with my second son, I bled small amounts, I had placenta previa(sp?) the bleeding started at 6 weeks didn't stop at all.

This is fairly common, and I have no idea why it might happen.

You should give your doctor a call and ask about it. Chances are it's nothing to worry about, but there are some things you don't bet on no matter what the odds are :) If nothing else, your doctor will be able to give you a well-grounded answer that will reassure you more than anything anybody here can say would.
