I need to pee but nothing comes out? Help xx

So I woke up this morning absolutely busting to pee and so I went, but almost right away I felt like I needed to go again but my bladder is empty? It sounds like a UTI and I've had it before, I've also taken some stuff for it but do you girls have any recommendations of how to help the need to pee go away?
I have a flight in the morning and I don't want to be uncomfortable the whole time 😭
