I've been on the pill (ortho-tri-cylen-lo) for 3 months and have unprotected sex with my boyfriend (we're both clean) a few times. I've only taken the pill late once, and that was the placebo pill. My period is a few days late, even though I'm having cramps, and I'm panicking just a little bit that I may have gotten pregnant, even though I had my period last month after we had sex. Long story short, please help!!!
