I had sex on 12 march and after that I had unwanted 72 on 13 march and after that on 22 march I took pregnancy test which was negative and on 23 I got bleeding of red and brown clots after that bleeding I have minor white discharge in my vagina but not on my undergarment and after that I again took pregnancy test on 5 april which was again negative but also I feel very low so is there a need to test again or am I safe from pregnancy.
