Doctor, there are few days left for my periods to start and I will have physical relations on 4th december and my last menstruation was on 1st november, my menstruation always delayed from the day it was last somehow during intercourse the condom gets torn and semen goes into my vagina and within 3 hours I take (i pill emergency contraceptive pill) and today is 9th december and I checked my urine pregnancy test which was negative. And sometimes due to the side effects of the I pill I also get mild pain in the abdominal and breasts (breast tenderness). I want to know how many days will it take for my periods to come or what are the chances of me getting pregnant.
