Hi! I had sex with my GF last 3 months(october 16- roughly), and that was the only time I had sex with her until now. We had protected sex( Condom& pull-out method; no leakage or whatsoever). She got her period after 1 week or 10 days after the intercourse. Normal period last for 5-6 days and had her period for the last 2 months(normal period and consider regular;not on BC). On the 2/1/2015 we had some fun(not sex), I did suck her nipple quite hard and rough fingered her. After I ejaculated in the toilet which was done by her, most of the semen were on the floor and only few amount that left on my hand. Of course I did wash it water and soap which I do it everytime after ejaculation. 1 or 2 day next she had this brown discharge that scared her and her nipples are sore for more than a week now(9days) but is less sore now unless she pinches it.What makes me worry about is I did a lot of research before this about what can or what can not to make a girl conceives. They say they can have regular period during pregnancy. She of course is also anxious about this. She keep worrying that she might get pregnant by what I did 3 months ago. She is also facing indigestion.
