It's normal to have to pee often when you're pregnant. Early in your pregnancy, your body produces a hormone that may increase urination. In your second and third trimesters, your expanding uterus pushes down on your bladder. The pressure can wake you up several times a night to go to the bathroom. You may also have the urge to go even when your bladder is almost empty. This problem usually goes away a few days after your baby is born.

Call Doctor If:
It hurts or burns when you urinate. You may have a urinary tract infection. This should be treated right away.
You have the urge to go again immediately after you emptied your bladder.
You also have a fever.
There is blood in your urine.

Step-by-Step Care:
Drink plenty of fluids to avoid dehydration.
Try to drink fluids mostly during the day.
Drink less in the evening and at night. This should help you cut back on nighttime bathroom visits.
Avoid coffee, tea, colas, and other caffeinated drinks. These can make you urinate more often.
Avoid tight-fitting pantyhose, underwear, or pants.
