In the first trimester, certain hormones your pregnant body makes can stimulate urine production and the urge to pee. As the baby grows and the uterus expands, the bladder, located directly in front of the uterus, gets compressed. This means the bladder probably holds less urine before you develop the urge to pee. These forces conspire together to make pregnant women pee a million times a day. It is important to remember that if you feel you are peeing an unusual amount with burning, you might have a UTI. Talk to your doctor about doing a urine culture.
What can help you stop peeing so much, you ask? First, don’t stop drinking fluids. You need them to stay hydrated! But you can cut down on them right two to three hours before you go to bed to avoid so many nighttime interruptions. Avoid caffeine drinks if you can. In the third trimester, try positional changes to avoid compression of the bladder by the uterus.
