A chemical pregnancy is a type of very early miscarriage that occurs when an egg is fertilized but not fully implanted in the uterus. In a chemical pregnancy, the pregnancy disappears before the fifth week. Chemical pregnancies (also known as biochemical pregnancies) are very common. Chemical pregnancies can also occur after IVF. You can find more information below.
What is a chemical pregnancy?
A chemical pregnancy is an early pregnancy loss that occurs shortly after implantation. This type of pregnancy loss accounts for 50 to 75 percent of all miscarriages. Chemical pregnancies happen before ultrasound can detect a fetus, but pregnancy tests can clearly identify a pregnancy. Because chemical pregnancy occurs a few weeks after a positive pregnancy test, it can unfortunately have a devastating psychological impact.
Chemical pregnancy causes
The exact cause of a chemical pregnancy is unknown. But in most cases, miscarriage is caused by problems with the embryo, possibly resulting from poor quality sperm or eggs.
Other possible causes may include:
- abnormal hormone levels
- Uterine abnormalities
- implantation outside the uterus
- Infections such as chlamydia or syphilis
Being over 35 increases the risk of a chemical pregnancy, as does some medical problems. People with blood clots and thyroid disorders are also at greater risk than normal. Unfortunately, there is no known way to prevent a chemical pregnancy.
Chemical pregnancy symptoms
There may be no symptoms of a chemical pregnancy. Some women miscarry early without realizing they are pregnant. For women with symptoms, these may include menstrual-like stomach cramps and vaginal bleeding in the days after receiving a positive pregnancy result.
It’s important to remember that bleeding after a positive pregnancy test doesn’t always mean it’s due to a chemical pregnancy. Bleeding is also common during implantation, where the embryo attaches to the uterus. This process can tear or damage small blood vessels along the uterine lining, causing blood to be released. This condition often appears as a pinkish or brownish discharge ( discharge during pregnancy ). This is normal 10 to 14 days after conception.
A chemical pregnancy usually does not last long enough to cause pregnancy-related symptoms such as nausea and fatigue . This type of miscarriage is different from other miscarriages. Miscarriages can occur at any time during pregnancy. However, they are more common before the 20th week. A chemical pregnancy always occurs shortly after implantation. Some women may think they have a menstrual cycle, as most of the time the only symptom is menstrual-like cramping and bleeding.
Chemical pregnancy after IVF
In IVF, an egg is taken from your ovaries and mixed with sperm. After fertilization, the embryo is transferred to the uterus.
IVF is an option if you are unable to get pregnant for the following reasons:
- damaged fallopian tubes
- ovulation problems
- Uterine fibroids
- Other fertility issues
Depending on the clinic you use, a blood test is usually done within 9 to 14 days of the procedure to check for pregnancy. If implantation has taken place, the blood test results will be positive. But unfortunately, abnormalities in the embryo can soon cause a chemical pregnancy.
Having a miscarriage after IVF can be heartbreaking, but it’s also a sign that you might be pregnant. Your other attempts at IVF may be successful.
chemical pregnancy treatment
A chemical pregnancy doesn’t always mean you can’t conceive and have a healthy birth. While there is no specific treatment for this type of miscarriage, there are options to help you conceive.
If you’ve had multiple chemical pregnancies, your doctor may run tests to diagnose possible underlying causes. If your doctor can identify and treat the cause, this may reduce the risk of another chemical pregnancy.
For example, if an early miscarriage is due to an undiagnosed infection, taking antibiotics to clear up the infection may increase your chances of conceiving and giving birth in the future. If the miscarriage is due to problems with your uterus, you may need surgery to correct the problem and ensure a healthy pregnancy.
You should also know that chemical pregnancy is not the only condition that causes the body to produce excess pregnancy hormones. Higher pregnancy hormone levels may also occur in an ectopic pregnancy (ectopic pregnancy) . This is when an egg implants outside the uterus. Because an ectopic pregnancy can mimic a chemical pregnancy, your doctor may run tests to rule out this condition.
As a result
A chemical pregnancy doesn’t mean your body can’t have a healthy pregnancy. If you learn about the causes of early pregnancy miscarriages, you can get the appropriate treatment. This may correct the underlying cause.
You should talk to your doctor and consider your options. Your doctor can also provide information about support groups or counseling services. Because if you need emotional support after a miscarriage, they can help you.
