37 Weeks Pregnant

37 weeks pregnant: early term, baby movement and signs of labour

At 37 weeks pregnant, you are at the point many guidelines call early term. Labour can still begin any time from here, but if nothing is happening yet, it is still best for pregnancy to continue when that is medically safe.

This week follows 36 weeks pregnant and leads into 38 weeks pregnant. If you want to compare dates or due date estimates, use the pregnancy calculator.

Your baby at 37 weeks pregnant

The baby may be around 45 cm long and weigh roughly 2.5-3 kg, though estimates vary. Growth slows a little now, but the baby is still gaining fat and preparing for life outside the womb.

Many babies are already head down, with a stronger grip, more coordinated movements and a routine that may be easier to recognise. The intestines are filling with meconium, and the immune system continues to develop.

Movements may feel less roomy, but they should still be noticeable. If movements feel clearly reduced compared with your baby's usual pattern, contact your maternity team promptly.

Your body and symptoms

You may notice more pelvic pressure, vaginal discharge, tightening contractions, back pain and the need to urinate more often. Some people lose the mucus plug in one piece or in smaller parts, which can happen as the cervix begins to change.

Regular painful contractions, your waters breaking, bleeding or a noticeable change in how you feel are reasons to call or go in for assessment. If you are unsure whether what you feel is labour, it is better to ask.

This is also the stage where birth preparation usually becomes very practical: hospital bag, transport, support person, and a clear plan for who to call first.

What to do this week

  • Keep your hospital bag ready and check that you have the basics packed.
  • Know your labour contact number and the route to the hospital or birth unit.
  • Continue to follow movement patterns and report clear changes promptly.
  • Review your birth plan and the support you want if labour starts soon.
  • Rest where you can, because energy often drops again near the end of pregnancy.

Definitions

Early term is usually 37 weeks through 38 weeks and 6 days in many guidelines.

Mucus plug is the thick mucus that helps seal the cervix during pregnancy.

Labour signs include regular contractions, waters breaking and other changes that suggest birth may be starting.
