孕妇用英语可以说作 pregnant woman。"Pregnant" 是由拉丁语 "praegnantem" 演变而来的，原意是 "with child" 或 "carrying young".

例句：

The pregnant woman was due to give birth in a few weeks. (这位孕妇即将在几周后生产。)

The doctor advised the pregnant woman to get plenty of rest. (医生建议孕妇多休息。)

The pregnant woman felt the baby kick inside her. (孕妇感觉胎儿在身体里踢了一下。)
