What is the jelly-like substance that comes out of your vagina called?
is it part of urine?
explain why or why not.

It could be a yeast infection starting, it could be your ovulation days starting, your vaginal discharge will increase prior to ovulation.

If your period was unusual, you are not on birth control and had unprotected sex, did you take a pregnancy test? If not, maybe that's the first thing you might want to do.
