ivf and suboxone

Hey everyone! Has anyone ever done ivf while on suboxone? I'm just starting but my RE is insisting I come off. I'm on 1.5 mgs a day and have had a hard time going any lower. My sub doc who used to be an OB says he doesn't see a problem with me being on this dose and doing ivf. He said we would switch to subutex before the transfer. While I would love to not be on this med while pregnant I desperately want a baby and at 34 feel I need to get going sooner than later.
