Feels like UTI but it's not!!! (9 weeks)

April • Pediatric/ Family nurse practitioner and mother of 3: Celeste (9), Aniston (5) & Abel (Angel baby 16 weeks).
Hello ladies,
Wondering if anyone else is experiencing similar symptoms.
I have backpack and cramps and my urethra (the opening where urine comes out) feels "uncomfortable".
I feel like I have to pee constantly but not much comes out.
I went to doctor yesterday and my urine is ok. No infection. Baby looks good.
It's so frustrating. Anyone else? What helps?
