my girlfriend takes birth control. she tries to take it at the same time everyday but she is very forgetful and sometimes forgets to take it at the same time, or she will take it later, or sometimes forget to take it at all until later that day.
we have never had sex, but many times i will rub my dick on the outside of her vagina and clit, which i think is known as outercourse. i have never cummed while doing this, but i do precum. we did this a few weeks ago while on vacation, and now that it is time for her period, it has been 3 days late. when we were fooling around i never came. i also never came any time before that, and i did pee many times that day before we had outercourse. i read that precum can only get a girl pregnant if you came earlier that day, and then the precum can pick up the sperm from earlier that day. i also read that peeing after you cum will kill any sperm left in the urethra so that the precum cannot pick up any sperm on its way out since the urine killed it. is this true? and can my girlfriend be pregnant?
