I am a 24 year old female. I had my last period a month ago. It lasted for four days. On the fourth day, my fiance rubbed his genitals against mine. He did not ejaculate, still just to be sure, I took an I-pill within 12 hours. After a week, I noticed a brown discharge. On the next day, there was very little bleeding with clots, now it is the third day and the spotting continues. Usually, my period flow is normal, but this time it is very less. Should I consider this my period or withdrawal bleeding? When can I expect my next period? Also, my friend has also taken an I-pill. She experienced heavy bleeding after a week of taking it, and her next period got normalized exactly a month after she had her withdrawal bleed. Why is it not the case with me?
