question: Hi I m 17 and I m wondering if I could be pregnant, I had sex with my boyfriend twice a couple of weeks ago and. I was supposed to get my period on the 10th of this month but it s 11 days now and every now and then when I pee there is brownish pinkish blood on my undies but when I wipe there is blood I did a digital pregnancy test which was negative is there still a good chance I m pregnant .
