I had sex on 12 march without ejaculation and had taken unwanted 72 on 13 march (within 23 hours) and on 22 march. I get my pregnancy test done which was negative and on 23 march. I got some clots and bleeding of red and brown colour which last for 3 days so after that 3 days. I have very minor white discharge from vagina so is it a side effect of pill or is there any chances of pregnancy?
