on Sunday 13, me and my girlfriend had some naked grinding going on and immediately afterward I fingered her. At no point whatsoever did I ejaculate. Also, by this point she was three days late on her period ( not because she was pregnant, no sexual acts had occurred before this).
However, I panicked because of pre cM and she had a plan b( around 4 hours later) just to ease my mind. Now, ( 5 days later) on Friday 18th august, she said that she has some of her symptoms which she always goes through before having her period, ( she's also spotting since Thursday 17th august). is it possible that she will get her period now, 5 days after the sexual act and taking in the plan b (As she might have gotten the period she was meant to have before, which was late.)? Also, if it is not her period, but only some heavy bleeding caused by the plan B, does it mean that she is 100% not going to get pregnant. Or is there even a smaller chance of her getting pregnant?
