I recently had unprotected sex and the next day starting taking birth control. Without me knowing I couldn't have sex the first week on the pill, I had sex another two times and yes both times were unprotected also. After all this I am now 10 days overdue for my next period. I'm not sure if this is because I'm pregnant or because of my birth control ??? The only time I messed up with taking my pills was when I took my pill at 1:00am instead of 9:15pm. I don't know what to do!! Someone please help !!
