Babies born before 37 weeks are premature. A premature birth is more likely to happen when a mother has a health problem — like diabetes — or does harmful things during her pregnancy, like smoke or drink.
At 37 weeks, your pregnancy is considered full-term. The average baby weighs around 3-4kg by now. Your baby is ready to be born, and you'll be meeting them some time in the next few weeks.
In the past, a baby born anytime between 37 weeks and 42 weeks was considered "term." A pregnancy is now considered "full term" at 39 weeks.
Full term is now 39 weeks because research has shown that babies born at 39 to 40 weeks were less likely to have certain health problems than those born at 37 weeks. Babies born at 39 or 40 weeks instead of 37 or 38 weeks: Have more time for their brain, lungs, and liver to fully mature.
Gestational age is reported in 3 categories: pre-term (less than 37 weeks' gestation), term (37 to 41 weeks) and post-term (42 weeks and over).
At 37 weeks pregnant, baby is the size of a head of romaine lettuce. Baby measures about 19.1 inches. Average baby weight at 37 weeks is 6.3 pounds, and baby is gaining about half an ounce each day.
More than 9 out of 10 babies born at term (37 to 40 weeks) weigh between 2.5kg and 4.5kg. If your baby weighs 4.5kg or more at birth, they are considered larger than normal. This is also known as 'fetal macrosomia' and large for gestational age (LGA).
37 Weeks Pregnant is How Many Months? 37 weeks of pregnancy is approximately 9 months.
Your baby at week 37 of pregnancy
The average length of a baby at 37 weeks gestation is 19.1 inches (48.5 cm). Baby likely weighs 6.3 pounds (2.8 kg) and is packing on half an ounce (14 g) per day.
About half of all pregnant people will go into labor on their own by 40 weeks and 5 days (for first-time mothers) or 40 weeks and 3 days (for mothers who have given birth before).
Week 37 – your 3rd trimester. Your baby could come any day now – and this would not be considered early. Your baby is now "full term", which means that they're probably big enough, and mature enough, to survive in the outside world.
Ultrasound is not very reliable for estimating fetal weight near term. For a 9-pound baby, an ultrasound's predictive accuracy is typically 15 to 20 percent off. Which means we may over- or underestimate by more than a pound.
A larger than expected fundal height could be a sign of fetal macrosomia. Excessive amniotic fluid (polyhydramnios). Having too much amniotic fluid — the fluid that surrounds and protects a baby during pregnancy — might be a sign that your baby is larger than average.
Limit caffeine to less than 200 milligrams each day. Limit your intake of fish to 2 servings each week. Choose fish low in mercury such as canned light tuna, shrimp, salmon, cod, or tilapia. Do not eat fish high in mercury such as swordfish, tilefish, king mackerel, and shark.

The baby is still growing rapidly and could gain as much as an additional two pounds during the last four weeks of pregnancy.
The ideal weight of a newborn baby, who is born between 36-40 weeks, should be between 2.5 - 4.5 kg. A premature baby or any other such case will differ from baby to baby and is affected by several contributing factors. Health is one of the prime concerns of expecting parents.
By week 37, most mamas won't gain much more weight, as you're losing amniotic fluid, and baby's growth is slowing down.
