　　妈妈含辛茹苦的怀胎十月，为的就是能顺利生下一个健康的宝宝，为了胎儿健康，孕妇会经常到医院检查，那么怀孕八个月女胎儿图是什么样的呢?下面我们就一起来看看吧!
 
　　从怀孕八个月女胎儿图中，我们可以看到胎儿在头部在这个时期里会继续增大，大脑发育也非常迅速。
 
　　胎儿的大小：(第31周后)身长约43cm体重约1700g
 
　　子宫的大小：(第31周后)子宫底高度23~30cm
 
　　这个时期的宝宝大脑和神经系统已经发达到一定的程度，皮下脂肪继续增长。这时胎儿的眼睛可以开闭自由，大概能够看到子宫中的景象，孩子还能辨认和跟踪光源。但是可不能期待出生后的宝宝一开始就是个火眼金睛，通常孩子在刚出生的时候只能看到很近距离的东西，逐渐才能看到远处的物体和人。胎儿在子宫中被羊水所包围，随着胎儿的增长，胎动逐渐的减少。
 
        以上就是关于：“怀孕八个月女胎儿图是什么样的”的分享，希望对你有帮助。　　很多新手孕妇到了孕晚期就会担惊受怕，因为没经历过分娩也不懂得自己是不是快生了，一有风吹草动就觉得马上要生了，就会手足无措!但是也有可能是因为假性宫缩哦!如何辨别是不是假性宫缩?看这些特征!
 
　　如何辨别是不是假性宫缩?
 
　　什么是假性宫缩?
 
　　假性宫缩，也叫迁延宫缩。其特点是出现的时间无规律，程度也时强时弱。临产前，由于子宫下段受胎头下降所致的牵拉刺激，假性宫缩的情况会越来越频繁。在妊娠36～38周，子宫肌层处于不敏感的状态，较少发生子宫收缩的情况。在此过渡期后，子宫的不应期终止，完成一系列生理变化，为临产准备。
 
　　为什么会出现假性宫缩?
 
　　分娩前数周，子宫肌肉较敏感，将会出现不规则的子宫收缩，持续的时间短，力量弱，或只限于下腹部或腹股沟区。经数小时后又停止，不会导致子宫颈口张开、胎头下降，故并非临产，称为假阵缩。这种宫缩无规律性，无周期性，也不会有疼痛感。部分孕妇甚至在中孕期就能感受到不规律的宫缩。经产妇要比初产妇更为多见。
 
　　假性宫缩和真宫缩有何区别?
 
　　1、强度不同
 
　　假宫缩是没有规律的，宫缩的频率也不会加快，同时宫缩的力度也不会加强，子宫很硬，肚子发紧，孕妈改变个姿势等情况下反应会变弱，而且一般发生在腹部的下方，数小时后就会停止。
 
　　真宫缩是有规律的，宫缩的程度越来越强，频率更多，宫缩时间变长，间隔会缩短，不会通过更换姿势减轻痛感，而且会痛从腹部下方扩散到后背，之后可能会见红。
 
　　2、症状不同
 
　　真性宫缩还可能会伴随留血、胎头下降的症状，而且腹部会变得坚硬。
 
　　3、痛感不同
 
　　真性宫缩的疼痛是先从后背开始的，不久之后就会转移至前方，真性宫缩出现之后无论孕妇变换何种姿势，宫缩都会照样进行，事实上你的分娩已经开始，应做好分娩的准备。
 
　　4、最明显的区别
 
　　疼痛部位不同，真性宫缩最初是从后背开始疼痛的，同时还伴有见红、破水等其他症状，而假性宫缩的疼痛部位紧紧在腹部前方，且没有其他症状。
 
　　假性宫缩怎么缓解?
 
　　1、当孕妇大概判断自己是属于假性宫缩的时候，可以通过外界的一些小方法来缓解自己的不适应感。比如可以稍微冲个热水澡，放松下身体，缓解一下不适应感，这个时候最好有人陪同。再或者喝点水，有的时候出现假性宫缩可能是因为缺水的情况导致的。最后可以通过调节自己的呼吸来缓解痛感。
 
　　2、如果自己无法辨别的情况下，孕妇和准爸爸也不要太过于担心，立马去医院寻求医生的帮助，自己无法辨别万一是真宫缩的话，还是越早去医院的话越好，胎儿也会更加的安全。
 
　　3、需要注意的是，不要自行用药，以免药物使胎儿受损伤。服用药物一般也不能缓解，这时，孕妈妈要注意休息，尤其不能刺激腹部。
 
　　如何辨别是不是假性宫缩?看这些特征!假性宫缩和真性宫缩还是有很明显的区别的，对于很多第一次怀孕的孕妇还是要学会区别自己是不是假性宫缩哦!如果实在辨别不了还是要马上就医诊断比较好呢!
