Yeast? Fibroid? Detox?

Hi, wondering if anyone can help me out here. I posted vaguely about this in the Water Fasting forum but didn't get a whole lot of info on it.

Basically, I got my period just before my fast started, and it hung on for a few extra days later than usual...then things got weird. I noticed it was turning almost black in color with tiny particles. Ignored it, figured it'd stop.

It didn't, and it started to burn when I pee. Now it's lightened to a creamy tan color, liquid with little particles still, smells really unusual, the fluid is definitely coming out of my vag and not my urethra.

Now, I've never had a yeast infection in my life and this doesn't really sound like one to me...But what do I know? I've never had one. :/
I'm almost tempted to think it's a fibroid or some kind of uterine growth that's dissolving and coming out in discharge. But again, I don't know the symptoms of that kind of experience.

Any suggestions, helpful info, or relatable stories, anyone? Tweet
