What’s Happening to Baby in the Third Trimester

Babies are considered full term after 37 weeks. Full-term babies are 19 to 21 inches and weigh 6.75 to 10 pounds.

During the third trimester, your baby’s brain development is in overdrive. Her bones harden and she can open and close her eyes. After week 30, your baby puts on 1.5 pounds per week. Around week 36, she moves head-down to get into position for birth. After week 37, her organs can function on their own.

Third Trimester Prenatal Care

您在第三个学期（直到第35周），然后每周直到分娩时，您会在第三个学期与医生见面。

每次探访时，您的医生都会收集一个尿液样本，承受您的血压，测量您的基本高度，询问胎儿运动（踢计数）。您的医生还进行阴道检查，以查看您的子宫颈是扩张（开口）还是脱落（稀疏）。为了成功的阴道出生，您的子宫颈需要10厘米，而100％脱落。

请务必与您的医生谈谈您的感觉和您的任何症状。另外，现在是时候制定您的出生计划并决定哪种您在分娩和分娩过程中想要缓解疼痛.

在第36周左右，您的医生进行了B组链球菌测试，这是对必须接受抗生素治疗的婴儿有害的细菌。大约在同一时间，您的医生感觉到您的腹部，看看婴儿是否已经定居为出生的位置。大多数臀位（屁股）的婴儿自然会摔倒37周。
