I NEED HELP!! UTI OR PERIOD

So I woke up Sunday with a UTI. I had the burning and uncomfortable feeling. I went and got the Kroger brand of regular AZO…. It help still made blah. Today, Monday I am doing good drinking a lot of water and all. I came home toke a nap and then I started bleeding nothing heavy just some pink

Coloring and if I wipe it’s a little

Gloopy but nothing heavy.But it’s stinging really bad. I am suppose to start my period around this time but can this be from the uti? I scared to take more azo cause it said don’t take after two days and all! I don’t know what to do at all! I am so scared and just no one knows and I can’t call a doctor till later in the morning tomorrow.
