How soon after conception do you start producing the pregnancy hormone?
Conception usually occurs about 2 weeks before your next period would have been due (or about two weeks after the start of your last normal period). However, it takes about 6 days for your newly conceived baby to reach your uterus from your fallopian tube, and further 6 days for them to fully implant in the lining of your uterus, to start ‘interacting’ with your body. This ‘interaction’ involves your body providing your baby with nourishment through your blood stream, as well as your baby producing hormones that move into your body to support the pregnancy. Once the baby fully implants, they start to release a hormone called human gonadotrophin hormone (or HCG) into your blood stream. The HCG level starts off very low, but the concentration rapidly increases on the following days to produce physical pregnancy signs in the woman. (HCG levels also provide the basis for detecting a pregnancy with a pregnancy test.) This is the reason why early pregnancy signs do not start to become notice
