I have Pcos with 3x3 cm Right ovarian cyst detected in April 2014. After that I had medication till October 2014. After that I had regular periods with few months being little late. Off late now I had ipill in 16 hours of unprotected sex. Although we used withdrawal method and pretty sure semen didn't get inside. I was in 13th day of my calculated ovulation and menstrual cycle. Is there any chance Of getting pregnant?
