Ok I've been taking the pill for about two months now and I'm sexually active and my dermatologist told me to take an acne medicine with the pill it's called Minocycline and I don't remember her telling me it affected it or anything but my mom told me that it could affect it but I looked it up this month and it said its a moderate risk and some websites said not to worry cause only a antibiotic that helped a illness only affected it and last month I was fine I had my period on the first blue pill week so I don't know what to believe and I started my blue pill week yesterday and I haven't started bleeding yet I stopped the acne medicine about 3 days ago and I haven't had sex in probably like 2 weeks. Do u think I am pregnant? And can I still take a emergency contraceptive just in case?
