We had unprotected sex but before ejaculation we stopped and to rule out any chances of pregnancy I had unwanted 72 within 24 hours. After 3 days we had protected sex but I started bleeding in between and the bleeding become heavy with clots. To stop that I consumed tranexamic acid tablet 500 mg. The bleeding stopped in 3 days and after 3 days of that we again tried to have protected sex but I started bleeding again which was just a light bleeding which stopped in few hours. I don?t know what?s the reason of this bleeding every time I try to have sex.
