I take birth control regularly but have been on antibiotics for a few days. My boyfriend and I had unprotected sex but he pulled out before he came. I took plan B the day after because I was worrying myself so much. I do not normally get my period on the pill but will taking plan b mess that up?
The antibiotics could mess it up. If its effecting your pills it can cause breakthru bleeding. Be sure you use a condom the whole time you're on the antibiotic and a week after. Oh, what pill are you on, that can make difference? The plan B is going to mess with your cycle too.
Am sort of in the same boat. Took antibiotics while on the pill. Had sex, started to panic and took plan b. And then I got my period during week 3 of my pill pack. And it's been 5 period days. Hoping it slows down! That's never happened before. So now I'm wondering if I should start a new pill pack on Sunday to make sure I'm protected or still have my week on placebo/sugar pills.
