Causes & Risk Factors of Chemical Pregnancy
A chemical pregnancy is usually caused by chromosomal abnormalities in the fertilized egg. Other risk factors include:
- Age (higher risk for women over 35)
- Hormonal imbalances
- Thyroid disorders
- Uncontrolled diabetes
- Uterine abnormalities
- Lifestyle factors (smoking, excessive alcohol, or stress)
How is a Chemical Pregnancy Diagnosed?
1️⃣ Pregnancy Test
A chemical pregnancy is often detected when a woman gets a faint positive on a home pregnancy test, followed by a negative test a few days later.
2️⃣ Blood hCG Test
Doctors check hCG levels, which rise in early pregnancy. If they drop instead of increasing, it indicates a chemical pregnancy.
3️⃣ Ultrasound
Since a chemical pregnancy happens so early, an ultrasound usually does not detect a gestational sac.
