Usually a UTI has symptoms of low back, pelvic pain, frequency with urination, blood in urine, and/or pain/burning with urination. Sometimes people have a fever but not everyone
Well how does it feel when you pee. You would know if its a uti.
Sounds to me like maybe you have the flu... drink lots of fluids and take it easy. Hope you feel better.
If your fever gets any higher then go to hospital. Not good for baby.
