A chemical pregnancy is a term used for pregnancy detectable by early positive pregnancy tests, which ends in very early miscarriage, even before the start of the next period. Many times the woman does not even recognize that she was pregnant because the next period started as expected. The miscarriage occurred before the heartbeat could be detected on the ultrasound.
Most chemical pregnancies are due to chromosomal problems in the developing fetus. Other possible causes are inadequate uterine lining, uterine abnormalities both congenital and acquired like fibroids, low hormone levels, luteal phase defects, or certain infections.
There is no way to prevent chemical pregnancy. However, if repeated chemical pregnancies occur, genetic counseling is recommended.
According to the symptoms you reported, the possibility that you had a chemical pregnancy cannot be excluded. You might want to visit your gynecologist for further examination and follow-up about future pregnancies.
