I recommend that you go to see your doctor
, either your primary care doctor
or your OB GYN doctor, to help you figure out what is going on. The symptom you are describing might be "polyuria" - too much urine. It would also be important to know whether you have any pain with urination, any cramping of the bladder, any vaginal discharge, and any intestinal symptoms such as diarrhea or constipation.
One possibility would be that you have are having a urine infection. Usually pain and cramping are more prominent symptoms with a urine infection, but it is possible to have more vague symptoms, such as bloating and simply changes in the pattern of urination. Your doctor will be able to rule this out with simple urine tests.
Also, it will be important to rule out any vaginal infection
or anatomical problem with the pelvic structures. Sometimes after a hysterectomy, for example, the muscles of the vagina can become too relaxed, leading to partial prolapse of the bladder, called a cystocele, which can cause changes in urination habits.
Finally frequent or copious urination, polyuria, is sometimes a symptoms of diabetes, which can be ruled out with a simple blood test.
Talk to your doctor as soon as possible.
