ok, so I have been on aviane about 2 weeks when this happened, i usually take my pills at 930, i forgot to take it and woke up first thing and took it(2-4:00 a.m.) then my boyfriend came over and i thought he was using a condom(it was dark and he said he had one on), not only did he not have a condom on, but he also came inside of me, without me knowing. i know its gross but he said hes done it to many girls before and never got any of them pregnant(i just found out at that time.) im hoping hes sterile. ever since we had sex ive been having lower abdominal cramping, and thats it, sometimes being a little gassy. chances of me being pregnant?
