*妊娠子宮的增大有一定規律性。表現為宮底升高,腹圍增加。因此,從宮高的增長情況也可以推斷妊娠期限和胎兒發育情況。按孕月來說,第一個月末,子宮比孕前略增大一些,像個鴨蛋;第二個月末如拳頭大;第三個月末,子宮底約在恥骨聯合上緣2~3橫指;第四個月末,宮底達臍和恥骨聯合上緣之間;第五個月末,在臍下2橫指;第六個月末,平臍;第七個月末,在臍上3橫指;第八個月末,在臍和劍突之間;第九個月末,宮底最高,在劍突下2橫指;第十個月時,胎頭下降入骨盆,宮底下降回復到八個月末水平。

測量宮高的方法:讓孕婦排尿後,平臥於床上,用軟尺測量恥骨聯合上緣中點至宮底的距離。一般從懷孕20周開始,每4周測量1次;懷孕28~35周每2周測量一次;懷孕36周后每周測量一次。測量結果畫在妊娠圖上,以觀察胎兒發育與孕周是否相符。
