Three urine collection tests -normal. Why do I suddenly last few days have to pee so much No fever etc just keep running to potty. 54 years old?

Overactive bladder?: The two main causes of urinary frequency or urgency in women are urinary tract infection (UTI) and overactive bladder (OAB), i.e. increaed muscle tone or spasm of the bladder. Three negative urinalyses means you have no UTI, so OAB is the best bet, and you're at typical age for it.
