For the past 2 months my period have been so lite, its like I haven't got them. Last month my boyfriend and I had sex he came in me, I got my period 2 days after and it was really lite,and it was kind of on and of, I guess you could say spotting. That has never happened to me before and so I didn't really take much notice till now. Now I have my periods again and they are the same as last month its like I'm not bleeding and I don't no what to do... Could I be pregnant?.
