Im 18 and I had sex for the first time using a condom 3 weeks ago and then again 2 weeks ago, but was concerned that semen may have leaked because I found some on my leg near to my crotch but the condom didnt break. I was supposed to get my period 9 days ago (I'm fairly regular) but havnt had anything until today, I got really bad stomach pains and what I think is my period. There has only been a small amount of blood (not as much as usual, I'm kinda heavy) and its a lighter shade of red. I checked again to see if I was still bleeding and it's hardly anything now just like a bloody discharge. I did a pregnancy test 5 days after I was due on and it said negative, I did another and that said negative too but I'm worried that I am. I've been stressing out over being pregnant and i want to know is it likely that I am if only a tiny amount has gone into me? I've broken out in spots,and i have been slightly bloated but I'm not sure if they are signs im pregnant or just the stress..
