So I had unprotected sex (on a Friday) and took the day after pill. I then was prescribed birth control pills and advised to take them starting the next day (Sunday). My period was due to come the following Thursday but never did. Is this because I started the pills BEFORE my period instead of the Sunday after?
It's now been 2 1/2 weeks, I'm experiencing nausea and cramps. I was scared I was pregnant but I took two seperate at home tests that were both negative. Is the birth control possibly affecting my period by skipping and also causing symptoms?
