Help???

Lauren

Hi guys. Okay. So about a month and a half ago, I got my period for 18-19 days in a row. My doctor told me to stop taking the placebo week for my birth control, and start on the next week instead. Since then, that's why I've been doing. I heard and read that can make you not have your period. Since then, I haven't gotten my period and it is 24 days late. Since then, I have also had unprotected sex. Help??
