I've been on birth control for 3 months now and started my third pack this past Sunday. I always use condoms but today is supposedly when I was supposed to ovulate. My discharge is white and thick, and after a little research I read you can ovulate while on the pill? I had sex today, with and condom and no breakage. I've never missed a pill and don't plan on it. Should I be worried enough to go take plan b?
