i have been in a major dilemma lately and in an urgent need of someone's help. On 2nd November, 2015 i had sex for the first time with my fiance (and i had my last periods on 22nd October which means we did it on my 11th day ). it was completely unexpected, something that we did not prepare for. and we did without protection. to be honest, he did'nt actually penetrate his whole penis within me, neither did that session go on for long. he just penetrated once (or twice) really hard which tore off my hymen and then we stopped abruptly because it hurt me a lot.  Maybe if we continued to do so for 4-5 more mins, then he would have cum, so we stopped midway before he had to. but ever since then i have been getting weird stomach cramps and peeing frequently. at first i believed it was because i had sex for the first time so these are the after effects. but its been almost been 11 days since we did it and i still feel so bloated, stomach pain, a lot of gas and peeing frequently. and I'm highly tensed thinking whether I'm pregnant or not. i have heard from people that u don't get pregnancy symptoms in the first week itself, but i just find it strange as to why I'm feeling highly uneasy ever since i did it and the worse thing, the pain is not even ending. although like i said, he did'nt cum inside me and just penetrated once hard which tore off my hymen, I'm highly worried that his precum got to me. a week after that day, i even did my pregnancy test which turned out to be negative but i have also heard that pregnancy test don't work in the first week itself.later when i researched about this on net, i found out that if a guy urinates after his last ejaculation, then the precum would be sort of safe, and my guy ejaculated 2 days before we had sex which obviously means he urinated several times in those 2 days. but now whats getting me worried is these stomach cramps that doesn't seem to stop and also knowing that we did it on my 11th day which was close to my ovulation date. I'm highly tensed and i really need someones help about my situation ASAP. thank you.
