I got my hopes up and I’m scared

I told myself this month I would not become obsessed and get my hopes up but i feel I may have a uti so I need to see a dr for some antibiotics. When you get checked they test for pregnancy and if I go I will have to find out that way wether or not I am. I have 2 issues here, one, I just know it’s going to be negative and I’m gonna be let down once again and 2, if it were to some how magically be positive that’s now how I want to find out because that’s how I did with my first 😂I mainly tho just am so scared of being let down but I need to go to the dr from my symptoms. Period is due tomorrow.
