A chemical pregnancy is a miscarriage that happens before five weeks, immediately after the embryo implants (1）.It is a pregnancy that home pregnancy tests or blood tests may confirm but not seen on an ultrasound. It is also called a biochemical pregnancy (2）.

Most women do not know they are pregnant when they have an early miscarriage.约50 - 75%的流产都是化学怀孕的nancies(3）.读这篇文章来了解更多关于原因,chemical pregnancy signs and symptoms, risk factors, and diagnosis of chemical pregnancies.

Symptoms Of Chemical Pregnancy

Chemical pregnancy symptoms may vary from one woman to another. While some women do not experience any symptoms, others may notice the following miscarriage symptoms (2）.

• A positive pregnancy test that soon turns negative.
• Spotting for a week before the period is due
• Mildabdominal cramping
• Vaginal bleeding after a positive result
• Low HCG levels in a blood test

Causes Of A Chemical Pregnancy

While the exact cause is not always identifiable, it may happen due to one or more of the following reasons (3) (4）.

• Chromosomal abnormalities in the embryo
• Inadequate hormonal levels
• Improper implantation
• Problems with the uterine lining (due to anatomical, immunological, or other reasons)
• Low maternal weight

• A problem with the DNA of the sperm
• Low progesterone levels
• Unsuccessful IVF

Chemical Pregnancy And Clinical Pregnancy

The main difference between a chemical and a clinical pregnancy is ultrasound can confirm a clinical pregnancy.A gestational sac and fetal heartbeat are seen in clinical pregnancy, whereas not detected in a chemical pregnancy.

Risk Factors For Early Pregnancy Losses

The following factors may increase one’s risk of experiencing a miscarriage early in pregnancy (5）.

• Advanced maternal age
• Alcohol consumption
• Excessive caffeine consumption
• Cigarette smoking
• 有限公司caine abuse
• Blood clotting disorders
• Thyroid problems

• Certain maternal diseases—chlamydiaⁱXA bacterial infection spread through oral, anal, or vaginal intercourse,listeriaⁱXA type of bacteria that contaminates the food and causes listeriosis infection,syphilisⁱXA sexually transmitted bacterial disease, typically causing sores in the genital and oral regions, linked to fetal complications,toxoplasmosisⁱXAn infection caused by the Toxoplasma gondii parasite, typically found in undercooked meat, animal feces, and contaminated soil,vaginal mycoplasmaⁱXThe most common microorganisms to cause genital infections,ureaplasmaⁱXBacteria found in urinary or reproductive tracts and is primarily transmitted through sexual contact, etc
• Certain medications—venlafaxine, retinoids, paroxetine, NSAIDs, methotrexate, itraconazole, etc
• Obesity
• Previoushistory of miscarriages
• Abnormalities in the reproductive tract, such as uterine anomalies, short cervix, and uterine adhesions
• Exposure to toxins—pesticides, radiation, some gases, etc

Diagnosis Of A Chemical Pregnancy

Women who test positive in home pregnancy tests or blood tests and then test negative in the next few days might be asked to go for additional blood tests.If the pregnancy hormones show a declining pattern, it might indicate a chemical pregnancy (1）.However, these blood tests are not suggested for all women.

Treatment For A Chemical Pregnancy

As many women are not aware of their pregnancy until five weeks of gestation, miscarriage from a chemical pregnancy may be misunderstood for a usual or a late period. While some women may experience a little heavier blood flow with clots, others may have a blood flow similar to their usual period.

For women with Rh-negative blood group, the healthcare provider may administer a shot of Rh immunoglobulin after experiencing a pregnancy loss.An Rh-negative mother with an Rh-positive fetus might face some complications that may be avoided by the shot(6）.

These miscarriages occur early in the pregnancy, and for most women, they resolve naturally, and no treatment is needed. However, the recovery is quick, and the doctor may ask you to try again after one menstrual cycle (1) (2）.

Prevention Of A Chemical Pregnancy

While it is not always possible to prevent a chemical pregnancy, addressing some risk factors or intervening for treatable health conditions can help prevent a chemical pregnancy (5)

Chemical Pregnancies And IVF

According to fertility experts, a chemical pregnancyafter an IUIor IVF cycle is a good sign. This is because assisted reproductive technologies aid in getting pregnant. However, whether or not implantation and pregnancy will happen depends upon the body’s and embryo’s natural processes. Therefore, some IVF specialists consider a chemical pregnancy as good news as it confirms a woman’s ability to get pregnant and is a sign of hope that they will get pregnant in the future.
