Three weeks ago on 26th Dec, my boyfriend and I did genital rubbing but there was only pre-***. It was also during my period. He didn't go inside and ejaculated elsewhere(i'm sorry about the words usage). After approx 48 hours, I took morning after pill and exactly a week after that, i had heavy bleeding which looks like period. Is that the effect of the pill? A few days ago (which is three weeks after the incident), I took pregnancy test which gives out negative result. However, I am still worried. What are the possibilities? And when can I expect my next period? Also, I am having white discharge and feels like my period is going to start but it hasn't.
