Hello Dr. I wanted some advice on a problem my friend is facing All the days are calculated from the starting day of her last periods She indulged in an act of mutual masturbation in an afternoon of the 12th day after her periods started and she was worried about getting pregnant as the guy masturbated himself too during the act (he fondled the vulva after self masturbation when there was precum in his hands which he wiped but not sure he did or not. So when I was told about this I went to a chemist and asked for a solution and he gave an I pill which she took in the morning of the 14th day. There were signs of nausea vomiting and moods swings after taking the ipill. She also engaged in overexertion by exercising and running as it could induce miscarriage through early periods if she was pregnant. She also had sesame seeds and pineapple juice due to the same concern. On the 29th day (expected day for the next mensuration cycle) she had severe Cramp's and she got her periods but it was not the same as the normal one (it had a clot's which was brownish in color and happened only on the 1st day) and on the next day she got dark red clots and the flow wasn't much and had a light bleeding than the normal periods. Today is the 31st day There were no symptoms till today after her periods started on the 29th day such as nausea or vomiting but she had Cramp's Today is also the 4th day of her periods but she haven't got any. Could she be pregnant Are the abnormal period because of the ipill.
