Uti or kidney stone?

Claudia

So on Tuesday, I became very nauseous and felt like I needed to pee every few minutes. There was no burning, it would just feel like there was a blockage at the end of me peeing. The less I move, the better it feels. I started taking some uniary pain relief pills and they will semi help. Just wondering if anyone else has had a situation like mine and of I need on antibiotics or if I just need to let it pass. I have never had an uti, but I have had kidney stones before. Also, I am sexually active and we do not use protection.
