I have horrible anxiety to the fact I over think, well last month this guy and I were having sex and he came in me. I'm on birth control but because I am prone to over thinking I started to think that the pill failed and I didn't want to end up pregnant. Plus to the fact my nurse friend said to go take plan b. So I did. I went to the gyno for a check up and I got tested for pregnancy and I was tested negative 😊. But my question is because of the the birth control AND plan b hormones could that mess up my period for this month? since it still haven't come and I have 2 pills left in this month.
