要大家用英文来表达“怀孕”，你想到的第一个词就是pregnant吧，例如：I was eight months pregnant at the time. 我已有8个月的身孕了。当然如果你觉得这个词有点难度，可以用最简单的方式来表达：She is going to have a baby. / She is going to be a mother. / She is carrying a child. 这些同样是“怀孕”的意思。
但是“怀孕”这件事说得太直白有时也会让人觉得尴尬，所以英语里有不少关于它的委婉语，例如：
She has a bun in the oven.
这是一个比喻的说法，还是很生动形象吧。
She is expecting.
说完整了就是"She is expecting a baby." 另外"an expectant mother or father"就是指即将为人母/父的人。
She is in the family way.
这种表达或者是为了委婉，或者还可以作为一种幽默的表达。“让某人怀孕”可以说：put someone in the family way.
She is up the duff.
用于英国和澳大利亚，常指意外怀孕。
She is knocked up.
用于美国和加拿大，这个表达有些粗俗，有点女性在不希望的情形下怀孕的意思。“让某人怀孕”可以说：knock [her] up.
