So I had my period 7/13/13. I was expecting my period but it was 1 1/2 late. It wasn't even a "period". It was old blood. Didn't even last 2 whole days! It is now 8/26/13. Still having pms symptoms. (headache, bloated, kind of feeling pukey). Have not Bled one since. Took a pregnancy test today. Bpn. Could it be stress? Messed up hormones? Or pregnancy that doesn't want to show up yet? -Confusedd
