最近經常見到這裡既jm們不知在何時何年何日曾經用過綠d驗過得個哄，而冇用過任何其他較敏感度高的驗孕棒或，用過了但棒兒沒任何反應，更加冇去過普通診所或婦科診所、醫院進行過任何驗尿或驗血的方法驗孕，就斷言說自己有化學性懷孕。
讓我說說關於我化學性懷孕的小故事及看看貼出來有關化學性懷孕的資料，再決定自己是不是真的化學性懷孕吧！
今年三月份的某日，當時天真的我流啡時還以為是經期來，但第二天就很乾淨了，到第三天又來啡，我就覺得奇怪了，看看月曆，原來一直經期超準的我今天已經是day33了(我cycle為28-29日)，而且從來唔腰背痛的我竟然腰背痛、亦有胸脹痛、尿頻等奇怪現像，那就跟曾經懷孕的朋友請教一向，她們懷孕時是否有這類反應。經過她們的建議後，我就買來人生第一支驗孕棒，當時CB Ｄigital顯示 pregnancy 1-2 week，因為我正在流啡(作小產中)，所以朋友建議我去找個普通醫生驗証一下，再找婦產科醫生作一個婦科檢查。我下午跑到一間普通診所驗尿，當時只診所的棒棒只得淺線，所以醫生說太淺色未能寫紙給我証明。我跟老公說後，老公帶我到一個婦產醫生的診所，把ＣＢ及從那個普通診所帶來的驗孕棒給這位婦產看，他一看就說肯定是懷孕了，由於我兩次都是下午的尿液驗出來，而且當天已驗了兩次，所以他不用我再驗，就寫醫生証明給我，而經他診斷後就認為是作小產，把葉酸、縮合維他命、安胎藥給我帶回家，並且說我現在打仗中，只有50%陀得上，需要bed rest。
流了啡一星期後的一天就發覺身體都舒服了、腰背也沒有那麼痛，就心知不妙，特別叫老公買了盒綠d給我驗証一下，當時驗了兩次不是晨尿也有哄的，到第二天就流血入了急症，醫生當時在子宮頸照到舊異物，但不能肯定是水泡還是胎囊，叫我回家兩星期後把安胎藥吃完再照多次確認。回家後就痾了一舊粉紅色近肉色的組織出來。兩星期後回去也什麼都照不到，但我的脈像是轉變了，身體差了，西醫說我是化學性懷孕、中醫說我早期流產。
如果只係憑一支值一蚊幾毫子的國產早早孕檢測試紙就斷言自己有孕，未免太過兒嬉了吧，這樣想你自己也不會開心。
我昨天正是驗綠d有哄，今天驗ＣＢ Ｄigital就 not pregnancy，今天都已經day 34，雖然到現在都未有經期來，但假若明天就到，我也不會憑一支綠d有個哄仔就幻想自己就是化學性懷孕，希望大家對化學性懷孕的知識能加深了解一點。
第一步先要搵專業人士及方法確認你真的懷孕，如果連懷孕都未能証明到，何來可以談得上自己是化學性懷孕呢？
HCG數值於懷孕3-4 week時期，是每兩日咁雙倍增長，假設你真的小產，HCG數值都不會突然跌至0，所以你小產後都可能會驗到有孕，不過比較起較早前最高果時的HCG 數值可能較低而已。你可以於懷孕時驗血看一看HCG的數值，於疑似小產時再驗血，將兩個數值對比就知道答案。
Chemical Pregnancies: The Undetected Miscarriage
A chemical pregnancy is defined as a pregnancy loss that happens very early in the first trimester. In fact, chemical pregnancies tend to happen so early most women don’t even know that they’ve experienced one. Most health experts believe that in a chemical pregnancy the fetus actually dies almost immediately after conception. Nevertheless, for couples who are trying to conceive, experiencing a chemical pregnancy is no less upsetting than any other form of miscarriage.
How Common are Chemical Pregnancies?
Chemical pregnancies are much more common than you might think. In fact, between 50% and 60% of all first-time pregnancies are thought to end in miscarriage – a large majority of which can be attributed to chemical pregnancies.
The difference between a chemical pregnancy and most other forms of miscarriage is that many women don’t even realize that they have experienced one. This is because the vast majority of chemical pregnancies occur within the initial six weeks of pregnancy, when most typical pregnancy symptoms are not yet present, meaning that women is unlikely to take a pregnancy test.
Of course, with ongoing developments in pregnancy test sensitivity, women are becoming increasingly able to detect a pregnancy early on – as early as 3 days before a predicted period. As a result, it is likely that more women will begin detecting chemical pregnancies.
What Causes a Chemical Pregnancy?
Determining the reason for a chemical pregnancy can be difficult, however, there are a few known causes, such as:
- Chromosome Abnormality: Chromosomal abnormalities are by far the most common cause of a chemical pregnancy, and are present at the time of conception, preventing the baby from forming properly. As a result, a miscarriage occurs.
- Uterine Abnormalities: Abnormalities in the uterus, such as the presence of uterine fibroids, can interfere with implantation, leading to a chemical pregnancy.
- Hormonal Deficiency: Women with luteal phase defects and other hormone deficiencies have difficulty maintaining a pregnancy due to a lack of hormones. As a result, the body experiences a miscarriage.
Symptoms of Chemical Pregnancy
Women who have been pregnant before though, may notice that they “feel pregnant” prior to starting their period. That is because they will be experiencing some of the normal symptoms of pregnancy, such as:
- tender, swollen breasts
- nausea
- fatigue
Women experiencing these symptoms may also have a positive pregnancy test. However, a sudden reversal in signs of pregnancy and the onset of a period will indicate a chemical pregnancy has taken place. In addition, your may notice:
- small clots in your blood
- increased amounts of blood
- more severe cramping
Diagnosing a Chemical Pregnancy
Chemical pregnancies are primarily diagnosed by confirming the presence of pregnancy through a pregnancy blood test. Once a pregnancy has been confirmed, your health care provider will monitor your hCG levels to ensure that your pregnancy is moving along smoothly. If there is a sudden decrease in your hCG levels, this may signal a miscarriage.
If these levels drop, an ultrasound will likely be performed to detect any signs of life in the uterus. If a chemical pregnancy has occurred, no embryo will be seen and no heartbeat will be heard.
What is beta HCG?
[size=-1]Beta HCG "the pregnancy hormone" is produced by the cells of the implanting egg and can be produced in the absence of an embryo. Beta hCG can be detected in maternal plasma or urine by 8 to 9 days after ovulation. The chart to the right illustrates the normal rise and fall of hCG levels throughout pregnancy. hCG reaches a peak level at about 8 to 10 weeks and then declines for the remainder of the pregnancy [1]. | [size=-1]Concentration of beta hCG
Throughout Normal Pregnancy 
|
[size=-1]The "normal" ranges for the Beta hCG blood pregnancy test are shown in the table below.
Week from the Last Menstrual Period | Amount of HCG in mIU/ml |
| 3 | 5 -50 |
4 | 3 - 426 |
5 | 19 - 7,340 |
6 | 1,080 - 56,500 |
7 - 8 | 7,650 - 229,000 |
9 - 12 | 25,700 - 288,000 |
13 - 16 | 13,300 - 254,000 |
17 - 24 | 4,060 - 165,400 |
25 - 40 | 3,640 - 117,000 |
[size=-1]Because of the wide variation in values, the test is not useful in establishing the gestational age of a pregnancy.
[size=-1]Beta hCG levels should double approximately every 2 days for the first four weeks of pregnancy [2].
As pregnancy progresses the doubling time increases. By 6 to 7 weeks gestation beta hCG levels may take as long as 3 1/2 days to double [3,4].
[size=-1]You can use the Beta hCG Doubling Time Calculator [size=-1]to calculate the doubling time of two beta hCG samples by entering the date of the blood test and the corresponding beta hCG value for that day. If the hCG level is declining the the half life of will be calculated.
