At the end of the first trimester, the fetus is about three inches long.(在懷孕的第三個月末，胎兒差不多有三英寸長了。)

The use of any painkiller during the second trimester more than doubled the risk of the condition in a boy baby.(在這段時間使用任何一種止痛藥將使得寶寶的風險增加1倍。)

Mothers completed questionnaires within a few months after delivery regarding alcohol use during the first trimester.(這些孩子的媽媽們在產后幾個月內完成了有關“懷孕最初三個月是否有過飲酒經歷”的調查問卷。)

As you enter the third trimester, you’ve probably gained at least 15 to 20 pounds.(當你進入懷孕后期時，你可能已經增重了15--20磅。)

My doctor gave me the go-ahead to hit the slopes in my second trimester as long as I stayed below 10, 000 feet.(在我懷第二胎的時候，只要我保持在10，000英尺之下，我的醫生準許我去滑雪。)

Congratulations! By the end of this week, you'll have reached the end of the first trimester.(恭喜哦！到這周結束的時候，你也撐到了懷孕前期的末尾。)

As you reach the end of the second trimester, that little peanut in your belly is beefing up big time.(當你到了懷孕中期的最后時刻，你肚子里的小不點到了生長的重要時刻。)

Otherwise, you may want to wait until after the first trimester, when the risk of miscarriage declines.(其他情況下，你可以等到第一階段的妊娠期結束再講，那時流產的風險會小很多。)

I love sleep and I love my bed, but both deserted me in the third trimester.(我喜歡睡覺，我愛我的床，但在后期的時候他們都遺棄了我。)

Especially during the final trimester.(特別是在懷孕終期。)
