<!-- Definitions and diagnosis -->
Pregnancy, also known as gravidity or gestation, is the time during which one or more offspring develops inside a woman.[1] A multiple pregnancy involves more than one offspring, such as with twins.[2] Pregnancy can occur by sexual intercourse or assisted reproductive technology. It usually last around 40 weeks (10 lunar months) from the last menstrual period (LMP) and ends in childbirth.[1][3] This is about 38 weeks after conception. An embryo is the developing offspring during the first 8 weeks following conception, after which, the term fetus is used until birth.[3] Symptom of early pregnancy may include a missed periods, tender breasts, nausea and vomiting, hunger, and frequent urination.[4] Pregnancy may be confirmed with a pregnancy test.[5]
<!-- 定義與診斷 -->
’’’妊娠’’’（rèn shēn/ㄖㄣˋㄕㄣ）（{{lang-en|pregnancy}}），又稱’’’懷孕’’’，亦俗稱「有了」、有身，粵語「有咗」，是指{{link-en|子代|Offspring|胚胎或胎兒}}在哺乳類雌性體內孕育成長的過程[1]，而在哺乳動物中研究得最詳細的是人類的妊娠。人類的妊娠約40週，從[[受精]]排卵算起則為38週；妊娠始於{{link-en|月經|Menstruation|末次經期}}，經歷40週（10個[[朔望月|月]]）的孕期，[[分娩]]後即結束[1][3]。受精後的前8週發育型態稱為[[胚胎]]，分娩後則稱為[[胎兒]][3]。妊娠早期的症狀包含：無月經來潮、乳房柔軟度增加、[[孕吐|噁心嘔吐]]、飢餓與頻尿 [4]。多個胚胎的妊娠稱做{{link-en|多胞胎|Multiple birth}}，如常見的[[雙胞胎]][2]。[[性交]]或{{link-en|人工生殖技術|Assisted reproductive technology}}會導致妊娠，而妊娠可由[[妊娠試驗]]確診[5]。
<!-- Trimesters -->
Pregnancy is typically divided into three trimesters. The first trimester is from week one through twelve and includes conception. Conception is followed by the fertilized egg traveling down the fallopian tube and attaching to the inside of the uterus, where it begins to form the fetus and placenta.[1] The first trimester carries the highest risk of miscarriage (natural death of embryo or fetus).[6] The second trimester is from week 13 through 28. Around the middle of the second trimester, movement of the fetus may be felt. At 28 weeks, more than 90% of babies can survive outside of the uterus if provided high-quality medical care. The third trimester is from 29 weeks through 40 weeks.[1]
<!-- 妊娠期 -->
妊娠通常可分為3個時期。第一期定義為受精當週起算第1-12週。受精後所形成的[[受精卵]]，會經[[輸卵管]]向下移動，接觸[[子宮]]內層著床，並開始發育成胎兒與[[胎盤]][1]。第一期所承受[[流產]]（胚胎或胎兒自然死亡）的風險為三期之最[6]。第二期定義為第13-28週。在第二期中期，可能會感受到胎兒活動。第28週時，如果接受高品質醫療照護，大於90%的胎兒可在子宮外{{link-en|胎兒生活力|Fetal viability|存活}}。第三期定義為第29-40週[1]。懷孕初期因初著床，[[流產]]機率較高；懷孕中期開始，胎兒較易以儀器監測；懷孕後期，胎兒開始具備母體外存活能力，也因如此，法律和習俗多視懷孕後期的胎兒為個人。
<!-- Delivery and complications -->
Prenatal care improves pregnancy outcomes.[7] This may include taking extra folic acid, avoiding drugs and alcohol, regular exercise, blood tests, and regular physical examinations.[7] Complications of pregnancy may include high blood pressure of pregnancy, gestational diabetes, iron-deficiency anemia, and severe nausea and vomiting among others.[8] Term pregnancy is 37 weeks to 41 weeks, with early term being 37 and 38 weeks, full term 39 and 40 weeks, and late term 41 weeks. After 41 weeks, it is known as post term. Babies born before 37 weeks are preterm and are at higher risk of health problems such as cerebral palsy.[1] It is recommended that delivery not be artificially started with either labor induction or caesarean section before 39 weeks unless required for other medical reasons.[9]
<!-- 分娩與相關併發症 -->
{{link-en|良好的孕期保健|Prenatal care}}有助提升懷孕期身體狀況[7]，包含多攝取[[葉酸]]、避免使用毒品與酒精、規律運動、血液檢查與規律[[體格檢查]][7]。因妊娠而造成的{{link-en|妊娠併發症|Complications of pregnancy|併發症}}包含{{link-en|妊娠高血壓病變|Hypertensive disease of pregnancy}}、[[妊娠糖尿病]]、{{link-en|缺鐵性貧血|Iron-deficiency anemia}}與{{link-en|妊娠劇吐|Hyperemesis gravidarum}}等等[8]。正常孕期約為37-41週，以37週作為早產或足月的分界，在37-38週出生稱為早期足月產、足月產為39-40週、過月為41週；41週以上稱為過期妊娠。嬰兒在20-37週之間出生，稱為[[早產]]，可能會造成如[[腦麻痺]]等健康風險[1][中1]。如果在39週以前[[分娩]]，除非有其他醫療狀況，否則不建議進行人工[[引產]]或[[剖宮產|剖腹產]][9]。
<!-- Epidemiology, society and culture -->
About 213 million pregnancies occurred in 2012, of which, 190 million were in the developing world and 23 million were in the developed world. This is about 133 pregnancies per 1,000 women between the ages of 15 and 44.[10] About 10% to 15% of recognized pregnancies end in miscarriage.[6] In 2013, complications of pregnancy resulted in 293,000 deaths, down from 377,000 deaths in 1990. Common causes include maternal bleeding, complications of abortion, high blood pressure of pregnancy, maternal sepsis, and obstructed labor.[11] Globally, 40% of pregnancies are unplanned. Half of unplanned pregnancies are aborted.[10] Among unintended pregnancies in the United States, 60% of the women used birth control to some extent during the month pregnancy occurred.[12]
<!-- 流行病學、社會與文化-->
2013年全球約有2.13億次妊娠事件發生，其中1.9億次在[[發展中國家|開發中國家]]，2,300萬次妊娠則發生在已開發國家。在15-44歲年齡層中，每千名女性就有133名妊娠[10]。約10-15%已知懷有身孕的人因流產而終止妊娠[6]。1990年，因妊娠併發症而死亡的人數為37.7萬人，2013年則降至29.3萬人；其常見原因包含{{link-en|產後出血|Obstetrical hemorrhage}}、[[墮胎]]引起的併發症、妊娠高血壓、[[產褥熱]]與[[難產]][11]。全球約40%妊娠為{{link-en|非計劃懷孕|Unintended pregnancy}}，其中一半會選擇[[墮胎]][10]。在美國的非計劃懷孕中，60%女性曾在懷孕當月施行[[生育控制|避孕措施]][12]。
==已整併，非常感激==
妊娠（rèn shēn/ㄖㄣˋㄕㄣ，或稱懷孕、有身，亦俗稱「有了」（粵語「有咗」）），是指哺乳類雌性（包括人類）在體內有一個或多個胎兒或胚胎。人類的妊娠是哺乳動物中研究的最詳細的。
人類的妊娠從最後一次月經到分娩持續大約40星期（從排卵算起是38週）。分娩是生產的術語。
許多社會以及法律將妊娠分為三期。懷孕初期有很高的流產機率。中期開始胎兒就發展到可以跟蹤監測。後期胎兒就開始有母體外存活能力。由於這個能力，許多法律和習俗就視這時期的胎兒為個人。
