my underwear had precum soaked on it for sometime,it was only a bit moist, i rubbed myself on my girlfriend's vagina with my underwear on and also wore a condom, i did not ejaculate during the whole act and did not enter her either....after which she got very scared and feared pregnancy....so she even took a contraceptive pill within 10 hours of the act....my girlfriend also has PCOS..........a week later she experienced spotting.......and is very scared....is there a chance that she is pregnant? she also felt nauseas taking the pill and also gets abdominal pain........could she be pregnant?
