What causes frequent urination during pregnancy?

​​​​​​​​​​​​​​​​​​​​​​​​​​Pressure on your bladder caused by the growing uterus and baby can cause the need to empty your bladder more frequently. 

Increased frequency of urination in pregnancy is normal unless accompanied by symptoms of a urinary tract infection.

Some women may notice a decrease in frequency around the fourth month of pregnancy, but then an increase again as the baby drops into the pelvis toward the end of pregnancy.

Because you are at greater risk of developing bladder or kidney infections during pregnancy: ​

  • Drink plenty of liquids
  • Try to empty your bladder completely
  • Do not “hold” your urine when your bladder feels full
  • Notify your health care provider if you develop a fever, chills, backache, or burning with urination
