I don't have any personal knowledge about doses - I read this question on inciid and... well, I guess you can read their answer as well as I can :-)
If you don't feel safe with the instructions this doctor has given you, you might want to consider getting a second opinion. With problems conceiving, like with any medical condition, it's important to feel confident in your doctor.
Good luck,
