... My girlfriend and I had unprotected sex on 2 consecutive days only one day after her period had ended on oct. 10th friday. so that saturday/sunday we had some unprotected sex and everything was okay, i didn't ejaculate inside of her. on the tuesday (oct. 14) she took plan b one step just as a precaution. about 6 or 7 days later she noticed some light spotting which then turned into her regular period flow the next day. this spotting and full bleeding lasted for a total of 2/3 days and now its done. we are unsure as to what this could be or if everything is okay. could she be pregnant? is this a symptom of plan b? any ideas?? specific answers would help a lot!!
