I finished my periods on July 4th. My fiance and I were fooling around on 5th but he was wearing his underwear and we did not have intercourse.. but I was on top of him with his underwear on. His underwear was slightly wet. I took an i-pill on the 8th within 72 hrs. But now,11 days later, I'm having vaginal bleeding since 2 days. Is there a cause to worry? Can I be pregnant?
