This guy and I had sex with a condom on and I'm pretty sure he pulled out but I was not for sure as i had been drinking. I was also on my period (but very light) and I have been on the pill for 2 and a half years. I took 2 pregnancy tests a week after we had sex and they both came out negative. I feel very bloated and can hear things going on in my stomach and my lower stomach has been sore. Am I just freaking out too much or could pregnancy be a possibilty?
