I always keep track of my periods; I know if I had a heavy or light day, exactly when I am ovulating, and my period always lasts five days. I know I am pregnant but i'm not sure how far along. The online trackers don't allow me to take into account my own fertility or intercourse. My March period was from the 12-16. According to my calendar I was very fertile on the 29th and 30th. I had unprotected sex with my ex boyfriend on either the 30th or 31st, almost positive the 30th. I did get my period on April 12 - 16th however it was light the whole time. I had sex with someone else twice after that period but not sure of the exact dates, I know once was the 30th. I think I am pregnant by my exboyfriend I slept with in March but i'm not sure. I have been pregnant before and I know how my body felt, I feel like I am beyond the 3 weeks I would have to be if it was from after my last period. I can feel the soreness in my breasts, they have grown, there is a slight pudge in my stomach, my back is hurting, and my apetite has increased. I'm confused, which would be the most logical man responsible?
