More frequent urination usually occurs early in pregnancy when the uterus is expanding and pushing against the bladder. This sensation should improve in mid-pregnancy, but recurs again in late pregnancy, as the growing uterus and baby leave little room for a full bladder.

Limit fluids in the evening to decrease nighttime urination and disrupted sleep

Burning or pain with urination, consistent lower abdominal, or lower back pain may indicate a bladder infection which will require medical treatment.
