My boyfriend and I made out. He placed his, near mine but it never really went deep. But he ejaculated. To be sure, I took ecp in 2-3 hours after the incident (April 26). I had my first period (withdrawal bleeding, I suppose) on May 6 until May 10. The next month, I got my period on June 10-14 but it was lighter than usual. I am usually having irregular periods but after June, I haven't got period (or any signs of period) since July and now, it's September. Is it possible that I am pregnant?
