Is it normal to have a feeling of frequent urination and stinging when I go to the bathroom?

No. These symptoms can be consistent with a urinary tract infection. Patients usually also have a feeling of malaise, fever, and pain in the low back or below the belly button.
No. It is normal to go to the bathroom frequently when you are pregnant, especially as the baby gets bigger and begins tap dancing on your bladder. Stinging when you urinate is rarely normal and you should be evaluated for a urinary tract infection. Bladder infections should be treated quickly in pregnancy to avoid developing a kidney infection.
