Who is your doc?
I going to be blunt
1. topical avodart is worthless
2. If you get off for 9 months, if med kept alot of hair, you are going to be in for a massive shed, that may/may not grow back.
I understand you're wanting to play it safe, so I would talk to MORE than one doc about this. From my understanding, the meds only lower you chance, but don't have any effects on the fetus. But, when one's is talking about their future child, I guess that changes things.
