懷孕第33週

孕婦生理變化

妳的體重目前為止應增加10公斤至13公斤,在這懷孕後期每週增加450公克的體重是正常的,其中有約一半的重量增加由胎兒造成。子宮底是在肚臍以上12、3公分處,因子宮日漸膨脹使孕婦造成後期懷孕的不舒服日益明顯,如反胃、胸悶、易心悸、疲倦、呼吸困難等,但是由於胎頭正逐漸下降,這些現象以後會獲得改善。



胎兒發育成長

寶寶由頭至腳身長約為47.5公分,體重約為2000公克。在足月出生前的7週內,寶寶體重會急速上升,出生時的體重有一半是在這階段達成。寶寶的頭髮正在長出,指甲已長到指尖,胎毛則逐漸減少,皮膚的縐摺逐漸消褪。寶寶的生殖器也日趨成熟,如為男嬰,睪丸可能已從腹脛進入陰囊,如為女嬰,大陰唇則已明顯隆起,左右緊貼。



注意事項

1.雖然此時身體容易疲憊,但仍需維持適度運動如散步,以利生產。

2.孕婦的腰痠與腳、小腿腫脹現象仍持續,雖然腳易腫脹,仍應大量飲水。平時坐時可將腳抬高,躺時亦可以枕頭將腳墊高。

3.夫妻關係應減少,可改用彼此互相按摩來維持親密關係。

4.有一些孕婦乳房會開始分泌一些黃顏色的液體,這是初乳,與產後的母乳不同。

5.請預先安排下週的第六次產檢時間。





How your baby's growing:

This week your baby weighs a little over 4 pounds (heft a pineapple) and has passed the 17-inch mark. He's rapidly losing that wrinkled, alien look and his skeleton is hardening. The bones in his skull aren't fused together, which allows them to move and slightly overlap, thus making it easier for him to fit through the birth canal. (The pressure on the head during birth is so intense that many babies are born with a conehead-like appearance.) These bones don't entirely fuse until early adulthood, so they can grow as his brain and other tissue expands during infancy and childhood.
