My last period was on dec. 16 and my boyfriend and I had unprotected sex for the first time on dec. 30. Since then i've been really tired and hungry and my boobs were sore for a few days last week and I had an abnormal amount of discharge. Today jan. 10th i've had some really light bleeding a a little cramping. My period is usually regular and it wasnt supposed to come until the 12th and I always get major cramps on my period. I took a pregnancy test on the 8th but it was negative. Did I take it too early? Is it possible I could be pregnant even though I started having some bleeding today? Please let me know............
