My boyfriend and I have been having unprotected sex for the past year and a half and never gotten pregnant. He always makes sure to pull out before he well you know. But lately I have been having lower abdominal pains and i'm 5 days late for my period. I keep checking to see if it may just be cramps and see if my period started, but nothing. All I get is a white discharge. And the urination thing I can't go by that because I have a sensitive bladder. My breast are tender and enlarged but that usually happens right before my period, but I still haven't seen it. I can't say much about back pains because I have had large breast pretty much all my life and you know how that does on the back.
