I have a question about pregnancy... Its a little bit complicated but i will try to explain it as easy as posible...so lets begin My gilfriend and i had sex,almost one week ago...we did not use protection,any kind,but...my whole penis did not got in her vagina ,just the head of it,i puted it 2-3 times and it was there maybe just a few seconds...before that maybe an our ago i was in the shower and i masturbated... I noticed some white liquid on my head of the penis,but i did not cum,so should i be woried,is she pregnang or?
