So I want to say 2 weeks ago we had unprotected sex, then a week ago the condom slipped off so we went to get plan b, and also I should be about to start my period. But my symptoms are: dizziness, throwing up, cramps, White discharge and I don't know if it's from the pill, or my period, or if I'm pregnant!!! I tested maybe a week ago and got a negative. Possible too soon? I should be starting my period around 12-17th of this month
