Doctor's answer:
After cohabitation, the embryo starts implanting 7 days later, and it takes about 10 days to complete the implantation. Then it stimulates the trophoblast cells to secrete HCG. Therefore, you can determine if you are pregnant by checking the HCG level in your blood 10 days after cohabitation. It is the earliest method for checking pregnancy.
