Human chorionic gonadotropin is a hormone produced by the placenta after implantation.
A qualitative blood hCG test is ordered as early as 10 days after a missed menstrual period in order to confirm whether or not there is pregnancy.
In addition to a missed period, the earliest signs and symptoms of pregnancy might include:
- Tender, swollen breasts. Early in pregnancy hormonal changes might make your breasts tender, sensitive or sore.
- Nausea with or without vomiting.
- Increased urination.
- Food aversions or cravings.
