Can you still have your period while being pregnant?

Anda
So my question is what I titled the post and I was wondering what some of you may think. I do know that you can spot while pregnant but what I'm asking is if you can still have a normal 3-4 day (normal for me) period every month if you're pregnant. Now I'm assuming 3-4 months here. So ladies.... Any input?  -sorry if I've put this in the wrong group.
