　　怀孕三个月肚子多大?
 
　　怀孕3个月一般看不出肚子的变化的。一般情况在四五个月才能感到肚肚微鼓，但是因个体差异，有的可能会早一点或者晚一点。关于怀孕三个月肚子多大，我们可以通过怀孕三个月胎儿图去了解。
 
　　下面，我们就来看看怀孕三个月要注意什么。
 
　　怀孕三个月肚子多大
 
　　最近不少准妈妈心急地咨询到：怀孕三个月肚子多大?怎么好似还是不显形?不用慌张，下面由妈网百科告诉你当中的奥秘吧!
 
　　孕妇怀孕三个月的时候，肚子并不会很大，如果孕妇本身就比较瘦的话，基本上看不出来。
 
　　怀孕三个月的时候，胎儿长大约2-9cm，胎重约9-23g。宝宝的眼睛及手指、脚趾已清晰可辨，一部分骨骼开始变得坚硬，并出现关节雏形。这时宝宝四肢在羊水中已能自由活动，左右腿还可交替做屈伸动作。胎宝宝都在忙碌地运动着，时而踢腿，时而舒展身姿，看上去好像在跳水上芭蕾舞。宝宝在进入第三个月的时候才会开始被称为胎儿。第八周初胎头占整个胎儿全长的l/2，以后生长加快，至第十二周末身体重量增加1倍。这个时候胎儿内脏系统已开始具有功能，能吞咽羊水，变成尿液排泄出来。到了第十二周末，已显示成熟胎儿男女外阴的形态。
 
　　怀孕三个月的时候，胎宝宝已初具人形。这时胎宝宝的大脑体积越来越大，占了整个身体的一半左右。胎宝宝成长的关键器官将在两周内完成。往后的日子，孕妇发生流产的机会相应减小。
 
　　怀孕三个月的生理特征
 
　　怀孕的各个时期会有不一样的生理特征。准妈妈们应该了解清楚相应的特征，以更好地迎接新生命的到来。那么，当准妈妈们怀孕三个月时，会有什么生理特征呢?
 
　　怀孕三个月，孕妇的腹部逐渐隆起，怀孕特征越来越明显，一起来了解怀孕三个月孕妇的身体变化。痛苦的孕吐渐渐消失，这是由于胎盘替代了荷尔蒙的产生。再过两周甚至更短的时间，孕妇就彻底不会再感觉恶心了。孕妇的乳房正迅速地增大，由于腹部和乳房的皮下弹力纤维断裂，在这些部位出现了暗红色的妊娠纹。有些孕妈妈在臀部和腰部也出现了妊娠纹。
 
　　准妈妈腹部从肚脐到耻骨会出现一条垂直的黑色妊娠线，脸上可能会出现黄褐色的妊娠斑，这是怀孕的特征，在分娩结束后就会逐渐变淡或消失。现在你的乳房更加膨胀，乳头和乳晕的色素加深，有时你还会感到有些疼痛。这时从阴道流出的乳白色分泌物也有所增多。子宫随着胎宝宝的长大逐渐增大，孕12周时在肚脐和耻骨联合之间可以摸到子宫上缘。
 
　　此时孕妇的子宫底在脐与耻骨联合之间，下腹部轻微隆起，用手可摸到增大的子宫。现在，孕妇看起来很像个孕妇了，腹部开始变大，原来的衣服开始变得不合体了。体型变化大的孕妈妈，现在可以考虑穿孕妇装啦，把自己打扮得亮丽一些，做一个漂亮的孕妈妈吧!
 
　　怀孕三个月产检检什么
 
　　现代医学越来越发达，不少孕妇在怀孕期间都积极地去进行产检，以确保宝宝的健康。可是，产检项目众多，令人眼花缭乱，究竟怀孕三个月要产检什么?答案马上揭晓!
 
　　有些产检项目是孕期每次产检都需要做的，例如：测量身高、体重、血压等，通过这些检查孕妇的身高、体重来估算孕妇的体重增长是否正常，通过这些检查能够对孕妇整体的身体情况进行一个评估。
 
　　怀孕三个月产检项目有胎儿的胎心检查，通过听胎心可以判断胎儿是否存活，胎儿正常的胎心跳动是在每分钟120-160次。同时还可以通过B超查看胎儿的大小，推算预产期，这些检查结果都可以作为后面产检做参考。
 
　　在怀孕三个月的时候孕妇还需要做血常规、尿常规、肾功能、肝功能等一系列化验检查，可以判断孕妇是否有贫血、肝炎、肾炎等影响孕妇和胎儿健康的疾病。在产检的时候还需做心电图检查，查看孕妇心脏功能是否健全。
 
　　在怀孕三个月产检的时候还应该进行梅毒、乙肝六项、艾滋病等传染性疾病的检查，以确保胎儿能够健康的出生。
 
　　怀孕三个月需要做哪些产检?产科专家介绍：绝大多数正常孕妇做第一次检查(孕期初检)后，每4周检查1次，28周后每2周检查1次，36周后每周检查1次，直至分娩。
 
　　孕期有3个月了，在这个月份内一定要去做产前登记和产前初检，领取母子健康手册。选择一家信赖的医院作为产前检查和分娩医院。
 
　　怀孕三个月的注意事项
 
　　进入怀孕三个月了，孕早期马上就要过去了，这段时期是从怀孕第九周开始算起到怀孕12周结束。孕妇在怀孕三个月内非常容易流产，知道过了晕早期才算度过流产危险期，因此为了胎宝宝的健康，准妈妈们一定要了解和学习怀孕三个月注意事项。
 
　　1、怀孕三个月孕妇一定要保证充足的睡眠，中午一个小时的午睡裨益不少。此外，夫妻最好不要行房事，至少也需要节制，且避免压迫到腹部，时间则越短越好。
 
　　2、多和同事聊聊天，取得理解和帮助，工作上千万不要勉强，避免从事可能会使身体受到震动和冲击的工作。
 
　　3、在怀孕第三个月，孕妇容易发生便秘和腹泻。因此孕妇要多吃通便的食物，在日常饮食中要增加膳食纤维量。尽量不吃容易引起腹泻的食物。
 
　　4、怀孕三个月是最容易流产时期，孕妇应停止激烈的体育运动和体力劳动，不要担重物和长时间站立或蹲下，不宜旅行。同时要注意避免使腹部受压迫和挤压。
 
　　5、孕妇应至少在本月前进行初次的产前检查，建立孕妇保健卡，以后按医生要求做定期检查。
 
　　6、如果孕妇在怀孕三个月有下腹痛和少量出血，应立即接受医生的检查，因为有流产和宫外孕的可能性，千万不可放松警惕。
 
　　以上就是关于怀孕三个月肚子多大，怀孕三个与要注意什么的介绍，怀孕初期即怀孕的前三个月是胚胎发育的重要时期，这时候由于胚胎不稳，一旦出现意外则容易给胚胎发育造成伤害甚至造成流产。
