What is hCG?
hCG is a hormone produced by your placenta when you are pregnant. It appears
shortly after the embryo attaches to the wall of the uterus. If you are
pregnant, this hormone increases very rapidly. If you have a 28 day menstrual
cycle, you can detect hCG in your urine 12-15 days after ovulation.
