UTI and weird discharge ???

Meg

So i’m pretty sure i have a UTI because i’ve had the burning sensation and i have to pee allllllll the time but when i go barely anything comes out, so i am going to the doctor tomorrow, but i noticed my discharge is really weird???? nothing much has changed except i switched birth controls about 2 1/2 weeks ago. anyone know why discharge would look like this?? (i know your pee hole and your vagina are 2 completely different holes but i didn’t know if there was some possible correlation between the UTI and funky discharge)
