A chemical pregnancy is an expression commonly used to describe an early miscarriage which happens before the fetus can be detected by an ultrasound, and before the fifth week of gestation. It is quite common and is believed to affect up to 75 percent of all pregnancies that end in miscarriage.
Several things can be possible causes of chemical pregnancy including low hormone levels, deficient uterine lining, various infections, luteal phase defect, and other unknown reasons. The most common assumption is that chemical pregnancies occur due to chromosomal issues in the developing fetus.
Medically, this is not considered a miscarriage – in medicine it’s more like a cycle in which a pregnancy never happened than a true miscarriage, but it is also considered to be an early miscarriage by some people.
A woman may get pregnant even as early as two weeks after going through a chemical pregnancy. Chances of a healthy pregnancy are high after having a chemical pregnancy, according to experts.
