I've been having sore nipples over the past couple of weeks and I'm not due on my period for a little while longer approximately 2 weeks and I haven't been feeling sick or anything like that and I heard somewhere that sore and tender nipples were a sign of pregnancy and I know this website can't help me for sure and that I have to go to the doctor's and everything but I was just wondering if anyone thinks I could be pregnant because my boyfriend and I are trying to have a baby and everything. Could I be pregnant after one 3 times of having unprotected sex.
