Chemical pregnancy facts
化学怀孕是植入后不久发生的早期妊娠丧失。化学怀孕可能占所有流产的50％至75％。
化学妊娠发生在超声检查可以检测到胎儿之前，但对于妊娠试验而言并不为时过早。HCG，或人类绒毛膜促性腺激素。这是胚胎植入后产生的一种妊娠激素。您的医生可以通过测试血液来确认化学妊娠。
体验miscarriage阳性妊娠试验后仅一两周才能造成毁灭性。
A chemical pregnancy can have no symptoms. Some women have an early miscarriage without realizing they were pregnant.
For women who do have symptoms, these may include menstrual-like stomach cramping and vaginal bleeding within days of getting a positive pregnancy result.
重要的是要注意，妊娠阳性测试后出血并不总是意味着化学怀孕。植入过程中也很常见，这是胚胎附着子宫的时候。该过程会破裂或损坏沿子宫衬里的微小血管，从而导致血液释放。发现通常是粉红色或褐色的排放。这是受孕后10到14天正常的。
化学怀孕通常不会持续足够长的时间来引起与妊娠有关的症状，例如恶心和疲劳。
这种流产与其他流产不同。怀孕期间的任何时候都可能发生流产。但是它们在第20周之前更为普遍。另一方面，化学妊娠总是在植入后不久发生。由于最常见的唯一症状是月经样的痉挛和出血，因此有些女性认为自己的月经周期。
A chemical pregnancy can also happen afterin vitro fertilization（IVF）。从卵巢中取出一个鸡蛋，并与精子混合。受精后，将胚胎转移到子宫。
IVF是一个选择，如果您无法受孕：
- 受损的输卵管
- ovulation problems
- 子宫内膜异位症
- uterine fibroids
- 其他生育问题
A blood test is usually given within 9 to 14 days after IVF to check for a pregnancy, depending on the clinic you use.
Blood test results will be positive if implantation took place. But sadly, abnormalities with the embryo may cause a chemical pregnancy shortly thereafter.
IVF后的流产可能令人心碎，但这也表明您可以怀孕。IVF的其他尝试可能会成功。
The exact cause of a chemical pregnancy is unknown. But in most cases the miscarriage is due to problems with the embryo, possibly caused by a low quality of sperm or egg.
Other causes may include:
Being over the age of 35 increases the risk of a chemical pregnancy, as does certain medical problems. These include blood clotting and thyroid disorders.
不幸的是，没有已知的方法可以防止化学妊娠。
化学怀孕并不总是意味着您无法构想并获得健康的分娩。尽管没有针对此类流产的特定待遇，但有一些选择可以帮助您怀孕。
如果您患有多种化学妊娠，您的医生可以进行测试以诊断可能的基本原因。如果您的医生可以治疗原因，这可以降低另一种化学妊娠的风险。
For example, if an early miscarriage was caused by an undiagnosed infection, taking antibiotics to clear the infection can improve your chances of conceiving and having a healthy delivery in the future. If the miscarriage was due to problems with your uterus, you may need a surgical procedure to correct the issue and have a healthy pregnancy.
您还应该知道，化学妊娠并不是导致身体产生怀孕激素的唯一疾病。较高水平的HCG也可能发生ectopic pregnancy。This is when an egg implants outside the uterus. Since an ectopic pregnancy can mimic a chemical pregnancy, your doctor may run tests to rule out this condition.
A chemical pregnancy doesn’t mean your body is unable to have a healthy pregnancy. If you learn the reasons for an early pregnancy miscarriage, you may be able to receive proper treatment. This can correct the underlying cause.
Speak with your doctor and discuss your options. Your doctor can also provide information on support groups or counseling services. These can be critical if you need emotional support after a miscarriage.
