I had my periods on 19 march and sexual intercourse on 28 march after 24 hours of intercourse I took unwanted 72. After taking unwanted 72 on 9th day the bleeding started which lasted for three days and was very painful. So after a month on 29 april again the bleeding started which was very painful and lasted for three days. I don't know they were periods or anything else but literally I was not even able to stand on those days. And now I feel like i'm pregnant because my stomach feels bloated and always I feel a little cramping like periods. And also my belly button has come upwards like women feel in pregnancy. I'm worried a lot please tell me am I pregnant?
