宝宝发育与母体变化

胎儿的情况：

孕妈妈进入怀孕21周时，此时的胎儿体重大约有30克了，而身长则差不多有18CM了。从B超图中可以清楚的看到，此时胎儿的头发眉毛渐渐浓密，眼脸也清晰可见。小宝贝的脚趾甲、手指甲开始长出来了。宝宝现在平均一个小时要动50次，差不多是一分钟就要动一次呢！

母体情况：

你知道怀孕21周时，孕妇的肚子有多大了吗？此时的孕妈妈体重基本增加了5公斤左右哦。如果是爬楼梯或者走远一点的路，你会觉得呼吸急促，有点困难。在这个孕周期，双腿水肿可能会加重，所以一定要避免长时间的站立。

怀孕二十一周重点关注

孕中期怎样才能睡得更好?

现在你的身体已经慢慢适应了荷尔蒙和身体的变化，所以，你应该能够睡得好多了，尽管有时候也还会有腿抽筋、做奇怪的梦和鼻子不通气的现象发生。在孕中期，虽然你的睡眠情况有所好转了，不过，随着你精力的恢复，你可能反而不需要睡那么多觉了。这段时期你的感觉和睡眠都好多了，可以开始有意识地做一些锻炼，能改进你的身心健康，还能帮助你晚上睡得更好。 >>> 胎儿打嗝是什么感觉，胎儿打嗝的原因     >>>怀孕六个月注意什么? 

孕妇贫血对胎儿的影响有多大？

孕妇贫血是孕妇在怀孕期发生的一种营养缺乏症。孕妇轻度贫血对胎儿没有明显的影响，因为铁在胎盘中单向转运，优先供应胎儿；重度贫血时，会因胎盘缺血缺氧，导致发育迟缓、胎儿宫内缺氧、早产或死胎。孕早期低烧本身对胎儿影响不大，但要查明原因。细菌或病毒感染可能引起胎儿畸形。现在胎儿个系统气管已经发育成型，建议查彩超，确切的看胎儿发育是否正常。 >>> 孕妇早中晚期的正确睡姿（图）     >>>孕妈做不得的10种美容！

孕期夫妻生活，选择不压迫腹部的体位

怀孕期间，一般来说下面这些姿势适合准妈妈准爸爸采取：女方在上，女方跨坐在男方的身上，这种体位也不会压挤到孕妇的腹部；侧卧位，:男方躺在女方的体侧，从后面进入；后侧位，男方跪在女方的身后，女方跪着，双臂撑地；传统姿势，如果采用男上女下的姿势，要让在上面的老公伸开胳膊支撑身体，不要压迫孕妇的腹部。

本周饮食要点

怀孕第21周营养需求：

2、这个时期，胎宝宝会大量吸收孕妇体内所含的铁质，为防止缺铁性贫血的发生，孕妈妈应多吃富含铁质的食物，如瘦肉、鸡蛋，动物肝、鱼、含铁较多的蔬菜及强化铁质的谷类食品。有贫血症状的孕妈妈，可在医生的指导下补充铁剂。 >>> 怀孕六个月孕妇饮食方案      >>>孕妇用护肤品对胎儿有影响吗？
