My girlfriend was ovulating and i fingered her with potential semen on it, the day after she experienced pms like symptoms. what chance is there she's?

Sex education!: It's so important for young people to learn true facts about sex - it can make a big difference in your lives. As she was ovulating at that time, if you both are very fertile, it is possible - not likely, but possible. If it was just a day or 2 ago - Plan B can work. Otherwise wait to see if a period is missed - then have a test/exam. Best!
