1st, 2nd, 3rd Trimesters

The feeling that you need to urinate often during pregnancy is mainly caused by the pressure of your growing uterus on your bladder and increased urine production. You may feel like you need to urinate even when your bladder is almost empty, because the pressure on your bladder gives the sensation that your bladder is full. 

As your uterus grows and rises higher into your abdomen, the symptoms may go away. However, during the last month of pregnancy when the fetus moves lower in your uterus to prepare for labor, the pressure on your bladder will increase again and the symptoms will return. During later pregnancy, you may awake several times during the night needing to urinate. 

If the pressure on your bladder causes you to leak some urine, you can do Kegel exercises to help strengthen the muscles around your urethra. 

If you have pain when you urinate, or you often feel you must urinate again right after urinating, talk to your health care provider. You could have an infection.
