I would suggest doing a kidney ultrasound
just to check the status of your kidneys. The symptoms that you are describing could be due to impingement of the gravid uterus to surrounding structures specially the urinary bladder
although we usually see that during the third trimester.
Since UTI is already ruled out with a normal urinalysis
another consideration is a stone in the kidney or ureter
. Get an ultrasound just to check on the kidneys.
Best of luck and Thank you.
