Lately, a few days after my periods would finish, I have been getting this snooty-like discharge that would even hang down my vagina when I sit on the toilet. It's very thick, sort of like the egg whites. It has a yellow tint to it. Could this be a mucus plug?

I read on some forums that some ladies get their period while they're pregnant. Maybe they confuse it with implantation bleeding? If so, what's the difference between the two? Could this be just discharge from ovulation, and that I'm not pregnant?

My "period" has been on time. The only time it wasn't was when I took an emergency contraceptive after intercourse back in December (the condom broke) and it came exactly a week late. I was very paranoid during that time period.
