懷孕第29週

孕婦生理變化

子宮底部已在妳的肚臍上方9至10公分，妳的體重增加約8公斤半至12公斤。胎兒在肚子裡的位置仍不一定，有時是頭朝上，有時頭朝下。現在開始有些準媽媽的腹部會有一陣陣地發硬的現象，有些像是生產時子宮收縮，這是一種子宮假收縮的現象（Braxton Hicks contractions）。頻尿仍會發生，在這個階段是正常現象。



胎兒發育成長

寶寶的頭臀長約為26公分，身長約為42公分，體重約1250公克。胎兒的眼睛可分辨經過子宮壁進來的光為明亮的陽光或人造光。寶寶現在由於體積日益增大，相對地可在子宮內活動的空間也日益縮小，使得胎動減弱，但是還是會做踢腿或伸懶腰的動作。



注意事項

1.孕婦要注意休息，不要走太遠的路或站太久。

2.若有厲害頭痛、視覺模糊、手腳明顯腫脹，或體重快速增加等現象，需立即安排就診，看是否發生先兆子癇（preeclampsia）。先兆子癇是妊娠後期的一種產科病，特點為孕婦會有高血壓、蛋白尿及水腫發生。常見於第一胎，生產後病情會改善並康復。





How your baby's growing:

Your baby now weighs about 2 1/2 pounds (like a butternut squash) and is a tad over 15 inches long from head to heel. His muscles and lungs are continuing to mature, and his head is growing bigger to make room for his developing brain. To meet his increasing nutritional demands, you'll need plenty of protein, vitamins C, folic acid, and iron. And because his bones are soaking up lots of calcium, be sure to drink your milk (or find another good source of calcium, such as cheese, yogurt, or enriched orange juice). This trimester, about 250 milligrams of calcium are deposited in your baby's hardening skeleton each day.
