During the scan, you'll be given an estimation of your due date; confirmation that there are no visible abnormalities and that development is happening as it should, and the, err, number of babies in there. What's more, most sonographers will give you a long-awaited picture to take home with you, too.<\/p>

Your baby at 12 weeks<\/h2>

If you've got your scan<\/strong> this week you\u2019ll get to clap eyes on your baby for the first time and suddenly all that information about how she's growing and developing becomes real.<\/p>

You will probably get to see her heart, skull, spine and limbs<\/strong> on the scan and if she\u2019s awake you\u2019ll be able to watch her jumping about.<\/p>

At 12 weeks, she can move her legs and arms<\/strong> individually as she's developing the sorts of muscles we use to walk and run with. It\u2019s a little-known fact that, under the microscope, these muscles would look stripy.<\/p>

Her head is still big in comparison to her body but her neck is getting stronger so she's able to support it more easily now. She\u2019s also already developing unique facial characteristics<\/strong>. Scans are really quite difficult to see, however, so if she seems to have a boxer\u2019s nose, jug-handle ears and a Desperate Dan jaw, she probably won\u2019t have them when she\u2019s born (unless your partner is Desperate Dan, of course).<\/p>

Here's what else she's up to in there this week:<\/p>

12周扫描

这是你一直在等待的时刻。然而,“12周扫描”这个词有点用词不当,因为它可以安排在10到13周之间的任何时间。医院会给你安排超声检查,通常需要半个小时——前提是你的宝宝在玩球。

在扫描过程中,您将获得截止日期的估计;确认没有明显的异常,并且在那样发生发展,以及那里的婴儿的婴儿。更重要的是,大多数超声波记录都会给你一长遍的照片,也可以和你一起回家。

你12周大的宝宝

如果你有你的扫描本周,您将首次拍摄宝宝的婴儿,并且突然间的所有这些信息是关于她如何增长和发展成为真实的。

你可能会见到她心脏、头骨、脊柱和四肢在扫描中,如果她醒着,你就可以看她的跳跃。

在12周大的时候,她可以移动她的腿和手臂因为她正在开发我们用来行走和跑步的各种肌肉。这是一个鲜为人知的事实,即在显微镜下,这些肌肉看起来有条纹。

与她的身体相比,她的头仍然很大,但她的脖子越来越强壮,所以她现在能够更容易地支撑它。她也已经发展独特的面部特征.Scans are really quite difficult to see, however, so if she seems to have a boxer’s nose, jug-handle ears and a Desperate Dan jaw, she probably won’t have them when she’s born (unless your partner is Desperate Dan, of course).

以下是她本周在那里做的其他事情:

  • 眼睛距离仍然有点远,但正在慢慢靠近。她耳朵但是,包括内部和中间部分,几乎都是完整的。
  • 她长了一层很好的头发模糊桃子叫Lanugo,覆盖她的大部分身体,只会在怀孕结束时脱落。这有助于她在子宫中保持温暖。
  • 骨头正在发展中,随着软骨脚手架的中间位,她一直在铺设钙并变得艰难。骨骼继续这种骨化过程,直到青春期。出生时,她将有300个骨头,最终将被成年为206岁。
  • 胸肌对于她来说,她开始练习呼吸是足够的 - 这是一个长期的项目,她将继续在未来几周和几个月内磨练。
  • 她在成长手指和脚趾指甲床.Awww。
  • 这个她暂时停在脐带里回来返回她的腹壁,现在他们将留在那里。
  • 肝脏和肾脏当她开始吞咽羊水时,她有一个膀胱来储存尿液。
  • 她的肝脏正在生产红细胞和骨髓正在制作白细胞..
  • 你的胎盘几乎或已经完成,但会继续和宝宝一起成长,为她提供食物和氧气,并通过脐带摆脱她的废物。
  • 更充分地形成,现在将开始减速到更悠闲的110-160拍/分钟。

怀孕12周症状

当一切开始成形,子宫从骨盆中升起时,你实际上能够感觉到它,并且很快会发现你有一个小肿块,除非这不是你的第一个孩子,在这种情况下,你可能已经出现了。

肚子痛

子宫从骨盆逃脱意味着你会得到扭曲不适因为它是从悬浮在腹壁上悬臂的韧带自由而衡量。这被称为圆形韧带疼痛

韧带将获胜,但是当它发生时,您可能会在下腹部两侧感到一些略微尖锐或痉挛的疼痛。这显然是更讨论的妊娠症状但请放心,这只是你的身体在工作。

尝试避免突然移动,尤其是从坐着或躺着站起来时。如果疼痛不仅仅是不适,更严重,而不是偶尔来来去去去,或者你经历过流血的有了它,你应该给你的助产士团队打电话。如果你发现当你锻炼,休息并降低速度或强度。

你12周的肿块

李子婴儿大小

如果这不是你的第一次怀孕,那么你很有可能会有一个合适的小肿块。然而,如果你要生第一个孩子,你的腹肌可能会更强壮,所以不要担心在这个阶段腹肌是否仍然偏小。

你12周大的宝宝多大?

12周的宝宝的大小是关于小李子的大小 - 或周围的5.4cm.

怀孕日历12周

怀孕12周时,你的身体变化如何?

你的身体已经开始感到有点“与众不同”。

婴儿,胎盘和流体总共重约2磅.它可能听起来不大,特别是当你认为在最后三个月的时候,你会每周都会被收缩,但你已经感受到了差异已经存在。

如果这不是你的第一个宝贝腹部很可能会想:“我以前做过”然后突然以河豚鱼的方式跳出来。除非你在上一次怀孕后做了一些严重的腹部锻炼,否则你注定会在12周后看起来接近足月,或者,充其量,你会发现自己再也穿不上牛仔裤了。

怀孕第12周需要考虑的事情

筛选和诊断测试

除了约会扫描,你还应该得到筛查综合征和其他遗传条件的筛选试验大约在这个时候。这被称为综合测试,因为你有一个血液测试,可以测量血液中的特定蛋白质,还有一个扫描,可以测量婴儿脖子后面的液体量。这就是所谓的颈部扫描,它通常是你约会扫描的一部分,所以你不必再来两次。

他们结合了结果血液测试和扫描并为您提供表达为的结果风险因素例如每500人中有1人。这项测试并不完美——它是一项筛查测试而不是诊断测试——因此会错过一些患有唐氏综合症的婴儿。

如果你的结果被认为是高风险的,你将接受羊膜穿刺术,用一根小针从你的腹部采集羊水样本,然后送到实验室进行检测。

或者,您可以获得绒毛膜绒毛取样,这是类似的,但取而代之的是将胎盘附着在子宫壁上的绒毛膜绒毛取样。这两种方法都能给你几乎100%的确诊。然而,这两种测试都有风险。

有一个新的测试叫做,它代表了非侵入性产前检测,并且是一个筛查测试,具有大约99%的精度,但对婴儿没有风险。它目前私下可用。

告诉别人你怀孕的事

一旦扫描出来的方式,你可能会死于宣布你的怀孕到你最近和最亲爱的。你可能对他们的一些反应感到惊讶。有些人会立即说'恭喜' - 但你可能会听到这样的奇怪反应,例如“我不能将你视为妈妈”或者是计划的?'和其他无益的评论。

请记住,人们对这种稍微出乎意料的反应可能有他们自己的原因——也许他们一直想要个孩子却没有成功。很难告诉你知道的人会不高兴。如果你感到担心,也许可以考虑自己告诉他们,而不是和他们在一起,或者先给他们发短信,让他们私下接受这个消息。

当然,还有其他人只患上嘴综合征,最好忽略。

你还需要做出决定什么时候告诉你的雇主.直到孩子预产期前15周,你才有义务告诉他们。你可以根据你的到期日,在日历上的星期日之前去,然后倒数15周。

大多数女性决定在这一阶段之前告诉她们的雇主。一旦您的雇主被告知,他们有义务通过进行任何必要的健康和安全检查并在需要时对您的工作进行更改,确保您和您的宝宝在工作中的安全。

此外,在他们得到通知之前,你不能在办公室的墙上用一支大红笔开始为产假倒计时。它可能看起来很尖。
