怎么分辨受精卵着床和经前综合症症状

经前综合症指的是月经前几天，甚至是前几周出现的一系列生理和心理症状。着床则是受精卵植入母体子宫，也就是说你怀孕了。它们可能在月经周期的同一时间发生，很难区分开来。但是，只要仔细留意，就能发现两者的症状有一些不同。一起来看看吧。

步骤

留意受精卵着床和早期怀孕迹象

2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/5\/5e\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-2-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-2-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/5\/5e\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-2-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-2-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 注意绞痛症状。你可能会在怀孕初期感到腹部绞痛。你可能会在来月经时感到腹部绞痛，也可能在月经前出现这个症状。这是经前综合症的常见症状。着床痛与经痛相似。^[2]
   • 留意腹部绞痛的严重程度。如果特别痛，你应该去看医生。要是疼痛转移到身体另一侧，也应该去看医生。这两种状况都可能意味着身体出问题了。^[3]

4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/a\/a3\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-4-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-4-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/a\/a3\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-4-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-4-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 观察头晕症状。孕妇可能会觉得头晕，主要是因为激素变化。但是，有的医生认为这也可能是身体正在制造更多血给胎儿的缘故。^[6]
5. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/9\/9d\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-5-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-5-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/9\/9d\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-5-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-5-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 5 留意你是否更常觉得饥饿。有时候，即使是怀孕初期，你可能会比平时更常感到饥饿。如果症状持续超过一两天，可能是受精卵已经着床。^[7]
6. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/0\/05\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-6-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-6-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/0\/05\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-6-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-6-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 6 检查是否感到恶心。晨吐这个词并不恰当，因为孕妇在孕期中的任何时候都有可能感到恶心和呕吐。早在怀孕后2周就可能出现这个症状。^[8]
7. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/9\/90\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-7-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-7-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/9\/90\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-7-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-7-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 7 留意是否对某些食物和味道反感。怀孕初期的其中一个症状是突然对某个食物和味道反感。这个症状会引发晨吐（即使你之前很喜欢这个味道或食物）。^[9]
8. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/7\/7b\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-8-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-8-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/7\/7b\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-8-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-8-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 8 注意是否呼吸困难。这个症状最常出现在怀孕初期和后期。你可能觉得比平时更容易喘不过气来。不管何时出现这个症状，都必须告诉医生。^[10]
9. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/7\/76\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-9-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-9-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/7\/76\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-9-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-9-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 9 留意是否有一股金属味。有的女性在怀孕不久后，会感到嘴巴里有金属味。经前综合症不会出现这个症状。^[11]

了解经前综合症症状

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/5\/5b\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-10-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-10-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/5\/5b\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-10-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-10-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 检查背部是否疼痛。怀孕后期肯定会背部疼痛。但是，如果你想区别怀孕初期和经前综合症的症状，那么背部疼痛更有可能是经前综合症的征兆。^[12]
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/9\/91\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-11-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-11-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/9\/91\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-11-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-11-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 留意情绪状态。虽然怀孕和经前综合症都会导致情绪波动，但是后者更有可能引发抑郁。如果你觉得有点抑郁，可能不是受精卵着床迹象。^[13]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/6\/66\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-12-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-12-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/6\/66\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-12-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-12-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 注意腹胀。虽然你也可能在怀孕初期感到腹胀，但这个症状更常出现在经前综合症。腹部可能觉得紧绷。^[14]
4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/f\/f0\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-13-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-13-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/f\/f0\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-13-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-13-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 留意是否来月经。来月经是没有怀孕最重要和明显的迹象之一。^[15] 尝试在日历上标注来月经的日期，这样就能弄清楚下一次来月经的日期。如果某次月经没来，你就知道自己可能怀孕了。
5. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/9\/93\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-14-Version-2.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-14-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/9\/93\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-14-Version-2.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-14-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 5 考虑在家验孕，以得到确切的答案。想知道到底是怀孕还是经前综合症？最有效的方法就是在家验孕。你可以轻易在药房买到家用验孕工具，它们通常附带容易遵循的指示。^[16]
   • 你可以在应该来月经的2天前，或者在想弄清楚到底是经前综合症还是怀孕时验孕。有的验孕工具声称在应该来月经的2天前，就能测出准确的结果。但是，如果你想得到更明确的结果，不妨等到应该来月经的1周后才验孕。^[17]
   • 大多数时候，验血也只能比家用验孕工具早2天检测到激素。不要为了好奇而要求医生验血，保险不会帮你付这笔费用。^[18]

辨别相似的症状

2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/e\/e4\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-16.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-16.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/e\/e4\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-16.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-16.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 留意你是否变得情绪化。经前综合症使你的情绪容易波动，但怀孕初期也会这样。^[21] 两种情况都是激素变化造成的。^[22]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/4\/4b\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-17.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-17.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/4\/4b\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-17.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-17.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 检查乳房变化。经前综合症和怀孕初期都会改变体内激素平衡，使乳房感觉肿胀或有一点痛。如果你怀孕了，乳房可能会更胀。^[23] ,^[24]
4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/b\/b7\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-18.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-18.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/b\/b7\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-18.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-18.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 留意你是否感到很累。经前综合症和受精卵着床均会使你觉得非常累。你可能早在怀孕的第1周就觉得很累，主要是孕酮增加的缘故。^[25] 但是，经前综合症也会引起激素变化，使你感到疲惫。^[26]
5. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/5\/54\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-19.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-19.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/5\/54\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-19.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-19.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 5 留意头痛症状。激素变化也会引起头痛。所以，怀孕初期^[27] 和经前综合症都可能出现头痛症状。^[28]
6. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/8\/8d\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-20.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-20.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/8\/8d\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-20.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-20.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 6 注意是否有想吃某种食物的欲望。来月经前，你可能突然很想吃某些食物。^[29] 怀孕初期也会有这样的状况。有时候，孕妇会想吃比较奇怪的食物，但并非每个孕妇都会这样。^[30]
7. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/1\/1b\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-21.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-21.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/1\/1b\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-21.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-21.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 7 留意消化道是否有任何变化。如果是经前综合症，你可能会因为激素变化而便秘或腹泻。^[31] 怀孕也会造成类似的状况，但更有可能引起便秘。另外，这些症状在怀孕后期更严重。^[32]
8. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/1\/17\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-22.jpg\/v4-460px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-22.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/1\/17\/Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-22.jpg\/v4-728px-Tell-Implantation-Symptoms-from-PMS-Symptoms-Step-22.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 8 了解何时会出现症状。经前综合症症状一般出现在月经前1到2周^[33] ，并在来月经后的2天内消失。^[34] 着床和早期怀孕症状一般发生在月经周期的同一时间，如果受精卵没有着床，子宫内壁就会剥落，开始来月经。^[35]

小提示

• 如果你可能怀孕了，记得每天摄取含有叶酸的产前维生素，这对健康的胎儿发育十分重要。

警告

• 如果症状持续，请去看医生，确认自己的身体状况。
