I started the pill last month and waited until the day of the eighth dosage to have unprotected sex (and used the pull out method). My birth control told me to start the Sunday after my period but I waited until the Tuesday after my period for various reasons. I already experienced bloating and pms, and after reading online I read that those are also early signs of pregnancy. I was supposed to start my period on Saturday, it's now Tuesday. Did I alter my cycle or am I possibly pregnant?
