Hello! After I finished my period (August 12) I waited about 2 weeks to start my birth control again (I've been on it for almost a year). I started it August 26th. I've been taking it every night, not at the exact time but within 9-11:30 p.m. also I haven't missed one pill. I had unprotected sex September 10th and he came inside me. I was worried that I could be pregnant so I went and took Plan B one step. Am I OK or should I be worried that I could be pregnant?
