Hi Doctor,I had sex with my girlfriend on 4th day of her periods, 28th March late night after 12. I thought little bit of semen was left inside before I took it out. Next day on 29th March, she had an I-Pill at around 10 pm and everything was okay. On 4th April, she started vaginal secretion again. Color this time is black and brownish and there is no pain or anything as happens in case of periods. We are very much worried and really need a advice whether she is getting pregnant or is it the side effect of I-Pill or the remaining blood is getting discharged which was stopped due to intercourse on 4th day??? Please reply soon, what could be the possibilities and what should we do.... we don't want this pregnancy before marriage.
