I Just Started Taking A Med To Help My Blood

I just started taking a med to help my blood pressure I already take losartan potassium 100mg and amalodipin 5 mg and the doc added hydroclormthzide 12.5mg it's a water pill and I am hardly peeing at all even after during water and cold drinks I've only took it once I've always had good urine output should I stop taking it, could it be bad and my bp is higher than it was .
