On a different note, I had a weird discharge from my vagina yesterday. After I did my dilation, I sat down to pee, as usual. And while I was peeing, this brown, semi-solid, icky thing came out of my vagina. It was about 1.5 inches long. Here is a picture of it (warning, it looks really gross!):

My first reaction was 'OMG this looks bad'. I briefly wondered if it could be feces. But I'm a pretty rational person so I didn't really panic. If it was feces, it would indicate a fistula... but the thing is, all throughout my recovery I always passed gas normally, and my feces always came out of my rectum and not my vagina, even when I had loose stools. I had never had any brown colored discharge from my vagina before, not even a tiny amount. Also, this brown gunk did not smell like feces. It didn't smell bad at all - it just smelled like damp paper or something like that. And the texture was not like feces either.
I fished out the brown gunk from the toilet, put it on a paper towel and took a picture of it. I sent an email to PAI to ask what Dr Burin thought of it. I got a reply within 12 hours (so quick, given the timezone difference!). Dr Burin said that it is normal and nothing to worry about. He said it's a mixture of old blood mixed with mucus, lubricant, and probably betadine solution (which I had been using to gently douche the inside of me recently as a precaution due to my UTI).
I think my vaginal canal must be pretty deep to be holding all these 'surprises' inside, haha! Since I am only dilating to 4-5 inches for now, I'm guessing that each time I dilate, I push all this gunk deeper inside my vagina. And it just kind of accumulates and bunches up deep inside? I had been douching recently, so maybe squirting the water inside helped dislodge this gunk and allowed it to come out.
