Feels like a UTI but tests were clear...?

So for the last few days I've had a lot of discomfort in my bladder area and i constantly feel like I have a full bladder even though I barely pee anything. I got tested today for a UTI but they said it was clear and sent me off without anything since I'm allergic to amoxicillin saying it's probably just pressure on my bladder. Is this normal?
