Last month my girlfriend and I "went through the motions" of sex without any ejaculation and out of the possibility of precum getting near her vagina she took Plan B. 2 weeks later (starting Feb 1) she got her normal period which ended around Feb 7). On Feb 14 we did the same but this time I wore a condom. Some semen seeped out the base and she felt it on the crease of her leg and groin. Out of fear that some semen got near her vaginal opening she took Plan B slightly before 24 hours following my ejaculation. 6 days later she had minor cramps that escalated to period like cramps and she got a one time bleeding that she said was a normal amount for her period, but she stopped bleeding immediately after. For the next 3 days she got a dark brown discharge she said she gets after each period. However, I'm pretty sure thats not her period. Her cycle is roughly 31 days slightly irregular and by then the uterine lining would be pretty near fully developed and she had her usual ovulation symptoms (she took the pill the day after she started getting them before any discharge from ovulation occurred). She is due in a couple days and got a bit of white discharge and has some mild, non-troublesome cramps. Is this normal? What are the chances of her being pregnant?
