I'm on lo loestrin fe me and my boyfriend had unprotected sex, he never came, i took a test my period didn't come why am i still worried?

Normal: It's normal to feel anxious about possibly being pregnant.... Especially at 16. It sounds like you are doing the right thing, though i would recommend adding condom because birth control isn't 100% effective at preventing pregnancy. Birth control pills, when you don't miss any pills, still only prevent pregnancy about 95% of the time. Best wishes, .
