如何知道懷孕幾周多少天了

要點(diǎn)提示：各項(xiàng)孕檢都需要正確的孕周來(lái)推算，寶寶究竟是不是正常的發(fā)育狀態(tài)，如果寶媽的孕周沒(méi)有算對(duì)，那么孕檢的結(jié)果就會(huì)出現(xiàn)一些差錯(cuò)

孕周對(duì)于寶媽來(lái)說(shuō)是非常重要的，除了計(jì)算預(yù)產(chǎn)期以外，各項(xiàng)孕檢都需要正確的孕周來(lái)推算，寶寶究竟是不是正常的發(fā)育狀態(tài)，如果寶媽的孕周沒(méi)有算對(duì)，那么孕檢的結(jié)果就會(huì)出現(xiàn)一些差錯(cuò)，比如在做唐氏篩查的時(shí)候，孕周沒(méi)有算對(duì)，就會(huì)出現(xiàn)高風(fēng)險(xiǎn)的可能，這樣的情況還有很多，如果沒(méi)有準(zhǔn)確的孕周，那么對(duì)于孕檢的結(jié)果就有很大的影響，如何計(jì)算孕周，是每一個(gè)寶媽都應(yīng)該知道的，特別是一些馬大哈寶媽們，自己的月經(jīng)又不是很準(zhǔn)確，不知道究竟是什么時(shí)候懷上的，這就更需要仔細(xì)的推算了，今天小編就給大家講講，如何知道懷孕幾周多少天了，孕周最準(zhǔn)確的計(jì)算方法是什么，趕緊來(lái)看看吧！

什么叫做孕周？

大家都知道，懷孕的一個(gè)標(biāo)準(zhǔn)就是停經(jīng)，所以我們只計(jì)算孕周的時(shí)候，也是通過(guò)月經(jīng)來(lái)計(jì)算的。雖然在月經(jīng)后的7天是安全期，懷孕的幾率很小，但是孕周本來(lái)就是一個(gè)大概的數(shù)字~所以計(jì)算預(yù)產(chǎn)期的時(shí)候也是在一個(gè)范圍之內(nèi)，一般來(lái)說(shuō)，只要是妊娠超過(guò)38周，就已經(jīng)屬于足月的胎兒，所以在醫(yī)學(xué)上面，孕周的計(jì)算是在最后一次月經(jīng)過(guò)后的第一天開(kāi)始！這也就是我們說(shuō)的孕周！

如何知道懷孕幾周多少天了？

因?yàn)榫雍吐炎臃謩e可以在女性的體內(nèi)存活2-3天，所以我們沒(méi)有辦法準(zhǔn)確的計(jì)算懷孕多少天了，只能大概的計(jì)算懷孕多少周！或者是大概多少天了，那么應(yīng)該如何推算呢？介紹幾種方法！

1.對(duì)于平時(shí)月經(jīng)周期比較準(zhǔn)確的女性來(lái)說(shuō)，只要通過(guò)計(jì)算排卵期的方法來(lái)計(jì)算自己什么時(shí)候排卵，在這個(gè)日期上面加上三天，就可以得到一個(gè)大概的范圍，這個(gè)范圍就是懷孕的天數(shù)了~

2.對(duì)于月經(jīng)周期不那么準(zhǔn)確的準(zhǔn)確的女性，是沒(méi)有辦法用推算的方法來(lái)準(zhǔn)確的得出自己的排卵日期了，這個(gè)時(shí)候我們就需要借助一些其他的方法，比如說(shuō)有記錄自己基礎(chǔ)體溫的女性，只要基礎(chǔ)體溫的曲線開(kāi)始下降，就說(shuō)明是進(jìn)入排卵期了（此處的下降應(yīng)該排除其他因素的干擾），我們可以通過(guò)這個(gè)下降的曲線來(lái)推算，在結(jié)合自己在那段時(shí)間的性生活，在加上3，就是可能受孕的日子！

3.從B超的結(jié)果來(lái)推算，B超可不只是為了看胎兒的性別的，我們可以從B超中看到很多我們想要知道的問(wèn)題，比如說(shuō)可以通過(guò)B超來(lái)看胎兒發(fā)育的情況來(lái)推算寶寶的孕周，不過(guò)因?yàn)槊總€(gè)寶媽的情況不一樣，胎兒的體質(zhì)也是不一樣的，所以這個(gè)會(huì)與實(shí)際的孕周出現(xiàn)一些出入，不過(guò)出入都在可以接受的范圍之內(nèi)！

以上就是小編給大家收集的關(guān)于孕周的計(jì)算方法啦，不過(guò)這些方法都還是有點(diǎn)出入的，想要知道自己最準(zhǔn)確的孕周還是去醫(yī)院讓醫(yī)生幫忙算算吧，這樣才是最權(quán)威的哦！
