What does it mean when a doctor says your hormone levels indicate that you're pregnant?

one hormone that is a good indicator of pregnancy is hCG which stands for human chorionic gonadotropin. it is only present if the woman is few weeks or maybe days pregnant. ask the doctor what hormone is he/she particularly referring to. as i know it, pregnancy test kits that can be bought in pharmacies measure the amount of hCG in the urine. --thoughtfulobserver
