I'm confused I already have a child with my boyfriend, but pregnant again, me and my child's father was on a break a while back and I ended up messing around. But in Jan he was the only one I was messing with my period ended in the 10th, my conception date was the 29th I'm confused because I messed with the other guy feb first but I believe I was already 1 or 2 weeks pregnant. I need help. I am nw 17weeks and 4 days
