so I'm really starting to freak about because I feel like I could be pregnant. My boyfriend and I were messing around on August 13th. I gave him a hang job and came in my hands and then he fingered me but when I asked him if he had any cum on his hands he said no. I've always had irregular periods and the last period I remember was in June.. And it's now September. I've been having cramps on the left side of my uterus and my breasts have been tender but maybe that's because I keep touching them to see if there's any sign of change. I haven't had any morning sickness and I took two home pregnancy test and they both came back negative. I'm seriously starting to worry because I've been reading a lot of stuff online. I have been really stressed out lately with school. Could I be pregnant?
