第12周：抵达孕早期终点线
宝宝现在的大小，相当于 一颗无花果.
平均长度: 5.4 厘米
（头到臀）
宝宝的发育情况
12 周啦！宝宝的所有主要器官、骨骼和肌肉都已经就位。循环、消化和泌尿系统开始工作，肝脏产出胆汁，指甲成型。宝宝已经在忙着练习喝洋水和排尿了。
妈妈的身体变化
恭喜您度过了一个重要的里程碑！到了 12 周，流产风险会显著降低。随着胎盘完全接手，您可能会感到精力充肺，孕吐消失，食欲大增。每个人的肚子隆起程度都不一样，哪怕现在还没显怀也完全不必担心。
给伴侣的小贴士
产检时您的陪同对她来说很重要。您可以帮忙规划路线、整理单据，或者备好水和零食。做一个认真的“带笔记员”，记录下医生的嘱托。这种并肩作战的感觉，能让她感到非常踏实。
