Hello - thanks for asking your question.
You note frequent urination with a normal urinalysis, STD screen negative and negative ultrasound of your ovaries.
There are a variety of causes that can cause urinary incontinence and frequent urination. I would first check a blood sugar level to make sure that diabetes is not present.
Renal function tests, calcium, and a vitamin B12 levels are other blood tests that should be checked.
Tests for a postvoid residual (i.e. using an ultrasound to see how much urine is left in the bladder after voiding) should be performed to further evaluate the cause.
The most definitive test would be urodynamic testing. These series of tests can evaluate an deficiencies in the musclature affecting urination. A urologist can describe various pelvic exercises that can improve the symptoms.
As far as I can see, your medications should not increase the frequency of your urination.
Followup with your personal physician is essential.
