Frequent urination and greater urgency are common symptoms related to pregnancy. Some women complain because there is the constant feeling to urinate, but little comes out.
What causes frequent urination during pregnancy?
Frequent urination is caused by a variety of pregnancy related reasons. Frequent urination is caused during the first three months as the growing uterus places pressure on the bladder. During the third trimester there is increased pressure from the enlarging uterus on the bladder. Additionally, frequent urination is often triggered again in the last weeks as the fetal head descends into the pelvis. Leaking is more likely during the third trimester, and you are more vulnerable to experience this when you cough, sneeze or laugh.
When does frequent urination occur during pregnancy?
Frequent urination may be experienced even before a missed period. It is a common first trimester symptom, but it is also experienced in the third trimester when the growing uterus is placing pressure on the bladder.
How frequently does frequent urination occur?
Frequent urination or at least a greater urgency to urinate is expected during your pregnancy. It is hard to find a woman who does not report that at some point she felt a great need to visit the restroom.
