Possible UTI?

Hey Ladies! So I recently had unprotected sex a few days ago and now I’m having a hard time urinating. Whenever I try only a little bit comes out. I have abdominal cramps but that could also possibly be from the plan B I took. I know, I wasn’t smart but does this sound like a UTI? I also took 2 at home tests and the Leukocytes were ranging high (125++) but the nitrates looked to be normal. This would be the first time I’ve ever had one so I’m just not sure.
