Hello

Help. I think I have a UTI. I've never had one before. It doesn't burn when I pee. But I constantly feel like I need to pee. I had my period two weeks ago. I'm on birth control. And took a pregnancy test this morning with a negative result. I need help. I pee and it still feels like I need to. I went to urgent care and they told me that the test for a UTI came back negative but my white blood cell count came back a little high (3+) and I had a little blood in my urine. I am on antibiotics but nothing is easing my mind. I'm scared I have a tumor or something. Please help me.
