Hi!
There is usually about 10 days between fertilization and implantation. The
embryoCea does not produce pregnancy hormone until implantation. So, there could be a 10 day gap between the time a conception occurs and the time we can detect it. That is probably why your doctor wants you to wait. If you don't want to be pregnant, be sure and use something during this wait time! If you were my patient and had both a neg test and no MP on the next set of tests--I would prescribe progesterone to start your period--I like to use
Prometrium because it won't harm a baby in case of an "oops".
Good luck!
Dr B
