When Does Nocturia Start in Pregnancy?

Needing to go to the loo at night (nocturia) is common in pregnancy (SHF 2013, NHS 2015a). It can start as early as the first trimester, sometimes going away in the second trimester before returning with a vengeance in the third (Wilson et al 2010).

How early in pregnancy does frequent urination start?

Frequent urination is an early sign of pregnancy and can begin as early as the first couple of weeks following conception. Most people, however, may begin to experience urgency in weeks 10 to 13, as this is when the uterus begins to push on the bladder.

Can early pregnancy cause frequent urination at night?

Frequent urination is a common early pregnancy symptom, but it can also reappear later on during pregnancy as your uterus and baby grow, putting pressure on your bladder. Although it can definitely be annoying, in most cases, it's nothing to worry about.
