孕婦生理變化
這時候的妳可以明顯感到胎動了。也許妳會有興趣每天固定的時間靜坐著聽音樂,數一數胎動,每一小時大概會出現3次至5次,在這同時也請爸爸一起和寶寶說話,這可聯繫父子與母子感情,也是一種胎教呢!妳的腰部曲線這時候大概已快消失了!流汗的現象也較以前嚴重,這是因為甲狀腺較活躍的關係。

胎兒發育成長
這時寶寶頭臀長大概有14公分-16公分,體重約有270公克。
寶寶現在可以聽到許多聲音:妳的說話聲、妳的心跳、妳腸胃蠕動的聲音、有時外界突如其來的聲音也會把他(她)嚇一跳!他(她)現在還會踢腿、翻滾、揮拳、伸懶腰了呢!此時羊水量分泌增加。

相關飲食
或許你已養成吃點心的習慣,然而,點心正是發胖的危險食物。如果餓了可以吃個不會胖又有飽足感的大蕃茄,嘴饞時,不妨可以吃些蒟蒻等高纖健康食品,既有飽腹感,還可以滿足口慾,並減少便秘發生。

注意事項
1.懷孕時尿道的平滑肌較鬆弛,易發生泌尿道感染,因此請勿憋尿,每天喝足量的水。
2.由於寶寶的成長會增加你的心肺負擔,請勿過度勞累。
3.20週以前胎兒離開母體稱為流產,過了20週後則稱為早產。

第三次產檢
1.問診:是否有不適症狀,如出血、腹痛、頭痛、痙攣等。
2.身體檢查:體重、血壓、腹長(子宮底高度)、胎心音、胎位、水腫、靜脈曲張。此時子宮底高度約為20公分。
3.實驗室檢查:尿蛋白、尿糖。
4.超音波檢查。

詢問婦產科醫師之問題:
1.胎兒的大小、體重與發育正常嗎?
2.由超音波看來,預產期在什麼時候?
3.我的體重增加是否正常?會不會太多?
4.我需不需要檢查血糖?

How your baby's growing
Your baby weighs about 10 1/2 ounces now. She's also around 6 1/2 inches long from head to bottom, and about 10 inches from head to heel. (For the first 20 weeks, we use measurements taken from the top of the baby's head to her bottom — known as the "crown to rump" measurement. After that, we use measurements from head to toe. This is because a baby's legs are curled up against her torso during the first half of pregnancy and are very hard to measure.)

A greasy white substance called vernix caseosa coats her entire body to protect her skin during its long submersion in amniotic fluid. (This slick coating also eases the journey down the birth canal.)

Your baby is swallowing more, which is good practice for her digestive system. She's also producing meconium (胎便), a black, sticky substance that's the result of cell loss, digestive secretion, and swallowed amniotic fluid. This meconium will accumulate in her bowels, and you'll see it in her first messy diaper (although a few babies pass it in utero or during delivery). 

How your life's changing
You've made it to the halfway mark — Congratulations! The top of your uterus is at the level of your belly button now, and you've likely gained about 10 pounds. Expect to gain an average of about another pound each week from now on. (If you started your pregnancy underweight, you may need to gain a bit more; if you were overweight, perhaps a bit less.) Make sure you're getting enough iron, a mineral that's used primarily to make hemoglobin (the part of your red blood cells that carries oxygen). During pregnancy, your body needs more iron for your developing baby and the placenta, and to keep up with your expanding blood volume. Iron-rich foods include lean red meat, poultry, fish, lentils and other legumes, spinach, and iron-fortified cereals.

If you haven't already signed up for a childbirth education class, you may want to look into one. Whether you're a first-timer or a pro, you can benefit from a structured class that helps prepare you for the rigors of labor and delivery. Most hospitals and birth centers offer classes, either as weekly meetings or as a single intensive, all-day session. Ask your doctor or midwife for a recommendation. At 37 weeks, you'll be considered full-term, so plan to be done with classes by then.
