i had sex with my boyfriend 4 days after my period! after we were finished, he pulled out with the condom on but it was only a little bit on about an inch, when he got up off the bed it slipped off. my period didnt come this month, but it doesnt come on time anyways. i have been stressed out about being pregnant, is there still a chance that i can be? when i look up information about appendicitis, i had about one symptom that was like appendictits...im worried please write back thanks!
