Could I be pregnant ? I had unprotected sex on the 5th and then again in the morning on the 6th, I was suppose to get my period 5 days ago and still haven't got it.. I've been cramping, had light brown discharge, loss of appetite/gain appetite.. Got nausea eating one of my favorite meals, which never happen before. Breast aren't sore but they look a little fuller and bigger. I'm not stressing either ! I don't go for a full physical check up until the 23rd, but I took a test on day 2 of my missed period it came out negative though.
