UTI or not...?!!

Al

I’ve drank two bottles of water and a cup of tea all in under an hour and now I have to pee, but after I go I still feel like i need to. my boyfriend and I had sex earlier today but I peed immediately after (as always) but I know a symptom is feeling like you need to pee but nothing comes out. no pain at all for me though. am I going crazy or is it something I should check out? thanks! ❤️
