Me and my boyfriend we're being frikking re****s. I decided to let him anal me and I'm worried that there was some pre-ejaculate near my vagina and maybe it somehow got inand may have conceived. However before that he had already ejaculated and also cleared his urethra by urinating and according to some sites I've visited that clears out the sperm in the pre-cum. I know that there's a low possibility, but there's still a chance and I'm now two days late from my period. I am aware that it may be from worrying about this for the past week however i am showing no signs of PMS symptoms. Another thing to note is that I didn't get any PMS symptoms last month or maybe the month before that either and that my periods are not always regular, because it came early last month for some reason. This didn't happen near my ovulation period (days 11-16?) either. So what are the possibilities of being pregnant?
