Some patients asked me about the term of “Chemical pregnancy”. I said it is an early miscarriage.
Here is the detail answer. This information is from online: http://www.babyhopes.com/articles/chemical-pregnancy.html
What Is A Chemical Pregnancy?
A chemical pregnancy is the clinical term used for a very early miscarriage. In many cases, the positive pregnancy test was achieved before the woman’s period was due but a miscarrige occured before a heartbeat was able to be seen on an ultrasound.
With the ultra sensitive pregnancy tests on the market today, it is easier than ever to get a positive result 3 or 4 days before your period is due. It is wonderful for those who NEED to know, but does have it’s down side. Early testing shows chemical pregnancies which would not have been detected had the woman waited for her period to arrive.
Chemical pregnancies are unfortunately very common. 50 to 60% of first pregnancies end in miscarriage very early in pregnancy. Most occur without the woman even knowing that she was pregnant.
What Causes a Chemical Pregnancy?
Most chemical pregnancies are due to chromosomal problems in the developing fetus. Other possible causes are inadequate uterine lining, uterine abnormalities both congenital or acquired like fibroids, low hormone levels, luteal phase defect or certain infections.
How can I Prevent Chemical Pregnancies?
Most chemical pregnancies can not be prevented. If you have recurring chemical pregnancies, your doctor should be able to investigate and help you formulate a treatment which is best for you. Potential treatments include vitamin B6 (at least 50mg a day), progesterone cream, and baby asprin. Be sure to discuss potential treatments with your doctor.
If infection is the cause, antibiotics prescribed by your Doctor can help.
