Third Trimester Of Pregnancy: Baby Development, Diet, Exercise, Warnings

Third trimester, the last trimester of your journey of pregnancy, begins with the 7th month of pregnancy and last till the time of delivery. When we talk about third trimester weeks, it starts from the 29th week and ends on 40th week or delivery.

Third trimester pregnancy is the most difficult and confusing time. You may actually think that your belly is fully grown and it cannot stretch more, but it is going to stretch more and your baby is going to be almost double in its size in just last three months of pregnancy.

Third trimester symptoms:

  • 3rd trimester fetal movement- With baby’s growth, space in your belly is reducing. You may notice frequent kicks and movement of baby.
  • 3rd trimester abdomen pain- During third trimester of pregnancy pain named as Braxton-hicks contraction of uterus becomes more prominent and may cause discomfort and pain. Pain is usually initiated by baby’s movement.
  • 3rd trimester bleedingBleeding in third trimester is not a good sign. It may be first sign of placenta previa or placenta abruption. Both require special medical management.
  • Third Trimester nausea- In last three month of pregnancy, uterus pushes stomach and shifts it upward. Female hormone progesterone, which is in excess in your body, relaxes the oesophageal sphincter. Upward pushing of stomach and relaxation of sphincter cause regurgitation of stomach food and acid. This is the cause of nausea in the last trimester.
  • Third trimester fatigue- In last month of pregnancy, fetus absorbs maximum amount of nutrition from mother’s blood, which causes fatigue. To ease this problem, take light juice and meal in every 3 hour. Try to relax mentally and physically both.

Baby Development in last trimester:

  • Fetal weight- Your ultrasound report may say that in 26-27 weeks your baby is only 1 kg, but your baby is going to double its weight in last three months. At normal Indian standard, here is the baby weight according to the week of pregnancy:
At 26th week About 1 Kg
At 28-30 weeks About 1.5 kg
At 32-34 weeks About 2 Kg
At 40th weeks About 2.5- 3 kg
  • Fetal bone- After 28-29th weeks, your baby’s cartilage transforms in bone. Now your baby needs more calcium and other minerals to easily perform this transformation. So be sure to take more calcium rich diet.
  • Fetal hair ( lanungo) – Fetal hair on its scalp and all over skin start growing. These first hair are known as lanungo.
  • Digestive system- In the 9th month of pregnancy, baby’s digestive system starts working. Baby’s intestine starts spasmodic action and actually starts producing waste product or stool. Baby’s first stool is known as meconium. Most of the babies pass stool within first 6 hr of birth, but it is also normal if baby passes stool during the time of labour.
  • Five senses- Now your baby can feel all the senses. Being in the dark close environment of belly, baby has developed the perception of light.  Your baby can now listen to you and other sounds. Sudden loud sounds also afraid him. So in the last trimester, you should be more precocious about what to watch, hear and talk, and what kind of environment you choose to be in.
  • Brain-Maximum growth of baby happens in last trimester and the interesting thing is that, 85% of growth of brain happens during fetus life. No more neurone is going to be developed after birth. So your baby’s future IQ and sharp mind develop when he is still in your tummy. So insure maximum nutritional life while you are pregnant and especially during 3rd trimester.
