Anyone else have had this or smell before???

Drea

I noticed yesterday I had this in the shower, it’s like crumb pieces. Today I smelled a sour smell like if it was a soar that popped near my vagina and when I cleaned it off it was a light light yellow color. I’ve had this before in the past but last time I had little soars around my vagina and when they broke out it had the same smell. I’ve been positive for chlamydia before and I’m afraid it is this. I’m curious if anyone else has had this?
