Dear Doctors, I started unprotected sex with my fence 2 months back, but I didn't dropped inside her, as a result her mensuration was normal. But after her last period I used condom at every meeting. Her period stars usually on 7th of the month, but this time her period yet not started. So, what may be the reason of her stopped period. And what should I do if her pregnancy test found positive, as I do not want any baby before marriage.
