自從發現懷孕這件事之後，雖然身爲醫學專業人士，仍然不免俗上網google了一圈，發現各種孕期筆記及建議并不專業，於是決定上網找指南，一方面指南有循證醫學證據，是經過大量研究總結出來，最具有專業性與指導性的。
爲了讓自己不要成爲記憶性缺失的孕婦，我決定寫下來給自己做筆記，如果你也看到了這個文章覺得對你有幫助。不過任何情況請請教你的婦產科醫師，畢竟每個人身體情況不同
以下是我摘要並翻譯美國婦產科指南的一些我有的（可能大家都有的）疑惑
【早期流產風險及相關因素】
The likelihood of early pregnancy loss occurring increases as a woman gets older. Early pregnancy loss occurs in more than one third of pregnancies in women older than 40 years.
About one half of cases of early pregnancy loss are caused by a random event in which the embryo receives an abnormal number of chromosomes. Chromosomes are the structures inside cells that carry genes. Most cells have 23 pairs of chromosomes for a total of 46 chromosomes. Sperm and egg cells each have 23 chromosomes. During fertilization, when the egg and sperm join, the two sets of chromosomes come together. If an egg or sperm has an abnormal number of chromosomes, the embryo also will have an abnormal number. Development will not occur normally, sometimes resulting in loss of the pregnancy.
【運動和性行爲不會造成早期流產】
Working, exercising, having sex, or having used birth control pills before getting pregnant do not cause early pregnancy loss. Morning sickness does not cause early pregnancy loss. Some women who have had an early pregnancy loss believe that it was caused by a recent fall, blow, or even a fright. In most cases, this is not true.
【可以適度攝取咖啡因】
Consuming 200 mg or less of caffeine a day (the amount in two cups of coffee) does not appear to increase the risk of early pregnancy loss.
【孕期飲食均衡搭配營養補充劑】
Although most of your nutrients should come from the foods you eat, it is a good idea to start taking a prenatal vitamin supplement before pregnancy. Prenatal vitamin supplements contain all the recommended daily vitamins and minerals you will need before and during your pregnancy.
【維生素補充】
Some medications, including vitamin supplements, over-the-counter medications, and herbal remedies, can be harmful to the fetus and should not be taken while you are pregnant. It is important to tell your health care professional about all of the medications you are taking during your prepregnancy care checkup. Do not stop taking prescription medication until you have talked with your health care professional.

【早期流產風險及相關因素】
生化妊娠 Biological pregnancy，是指最初受精卵著床，分泌微量HCG使妊娠檢測陽性，之後并沒有進入臨床妊娠，妊娠檢測轉陰性，隨後月經來潮。在受孕婦女，生化妊娠約15-20%。發生的最主要原因是受精卵的遺傳基因異常，無法正常發育。在以前科技並不發達試紙并不像現在敏感的時候，大部分的生化妊娠是不會被發現的，受孕婦女只會覺得月經晚了。生化妊娠之後的月經量可能會較以往量多，時間較長。
生化妊娠或早期流產的發生幾率會隨年齡增加，在40歲以上婦女發生機率為30%。但是發生生化妊娠不是你的錯，主要是受精卵質量不佳，這屬於生物淘汰的自然現象。
