Weird Burning

Hope • fellow human with vagina

Warning...this is a little gross! period ended about a week ago, and just today I started spotting brown gunk. Which, has never really happened to me before, but I read that it wasn't unusual. However, just now when I went to use the bathroom, it stings. Not that it stings to urinate, but the urine on my skin down there sting, like I've been cut. But there is no wound. I'm a little concerned...help!
