My bf and I had sex on 10th Oct at night.we had used condom but unfortunately when he pulled it out we found that his sperm has came out of the condom and I found some of his sperm on my vagina.but the condom has not split or broke.just then I felt some sensation like in my Lower abdominal area that night( Is that because his sperm has already entered my body) Next morning after 11 hrs I took an I pill.soon after I felt the same sensation with a little pain in my abdominal area including my back.It has been 6 days yet my body is showing the same symtoms..does I pill really works.? Is there any possibility of me to get pregnant?? Please help me out..what was that sensation for?
