This morning I woke up and used the bathroom (as I typically do first thing in the morning) and I noticed blood after I wiped, so figuring I had my period, I put on a tampon and moved on with my day. When I went to change it, there was no blood on it whatsoever, and it smelled terrible. I've also been noticing a white, thick, flecked discharge on occasion. I haven't been sleeping well, and my back is sore more than normal.
Could this just be a UTI, or should I be worried that it might be more serious? I'm confused, and I can't see my doctor until monday. Any advice?
