Okay so I've been on birth control for about a year now, a month ago I had unprotected sex with my boyfriend and he didn't ejaculate inside of me. 2 days after that I got my period as usual. This month there were 2 days were I had forgotten to take my birth control pill on time but took it as soon as I remembered. Yesterday I was supposed to get my period and it still hasn't come. I don't know if my period is delayed because I forgot to take my pill on time or if I'm pregnant. All answers are greatly appreciated, thank you!
