Hello, my gf was bound to have her periods on 16th august. She did not. On 19th, around 3.45pm,we became intimate, and at the start of foreplay, i had a little penetration of my penis for 2sec,unprotected.(i masturbated the previous night, n went to pee atleast 4times from next morning, that is on 19th morning, n washed my penis while taking shower. I did not ejaculate. Still asked her to take ipill, which she took on 20th around 10pm,she is still not getting her periods. Did even get other side effects of emergency contraceptive. We r very tensed. It was first time for both of us. M 24,she is 21
