Pregnant but still having periods?

[KGirl]

I dunno if this is in the right place, but I'm trying to see how many women have gotten pregnant but still have had normal periods during some of their pregnancies..

I've heard of some women that do bleed during their pregnancies - I doubt it is very common; and most of what I have heard/read is that it is women who have irregular cycles to begin with.
