I had sex with my boyfriend the day I got on birth control (so Yeah I know it didn't help) but we used a condom. But now I'm half a month into using the pill and my period is two days late (which has happened before) I think I'm paranoid. But I saw someone say your period doesn't come until the brown pills? Is that true? Is something wrong? Am I pregnant? Im only 18 and freaking out please help me
