I felt the same way at 7 weeks. It didn't feel like a UTI, but it felt strange to urinate. I went to doctors. They tested for a UTI and the test was negative. Doctor sent urine to the lab. Results came back i had an Iinfection. Antibiotics cleared it up. Insist your urine gets tested in a lab.
Most likely a UTI, course of antibiotics and plenty of water will sort ut
