I had sex on July 3rd, which happens to be in the date range that I would be ovulating. The condom broke, and about an hour later, I took Plan B (I'm not on any regular birth control for personal reasons). I had some cramps and maybe some fatigue the next day. Since then, I've had some vaginal discharge. I'm expecting my period on July 19th, and suddenly woke up being really nervous about it. I've taken Plan B once before in a similar incident (I generally try to be really careful). Basically, I guess I'm wondering if Plan B is just as effective during ovulation or what signs/symptoms I should be looking for.
