Im not having sex anymore cause my gf refuses to go on the pill due to family health reasons of cancer in the uterus. Last time i had sex was over 2 months ago and my gf isnt happy about it. anways, what is the final conclusion on the whole period idea. Some say a girl cant have a normal period while pregnant,but others say she can. What is the truth to this? I was just kinda worried cause my gf has been craving alot of food like junk food it seems like, and seems to have put on a few pounds but got heavy period she says for the past 2 months.
