I and my girlfriend had sex on 1st of this month at 4 Am and on the same day she had the I-Pill tablet at 4 Pm and next day on 2nd sept we had sex twice same day but I did not had intercourse and yesterday night (14/9/17) she had a little bleeding brownish in colour we thought it is periods but she didn't had the bleeding today but there's pain in her stomach (15/9/17) why it is so? Ist because of I-pill tablet symptoms or is this symptoms of pregnancy? Please any Dr. can answer me accurately I will be thankful.
