Well, God's grace is with those who seek Him. You need to look into your heart, into your reasons for becoming Orthodox. I had to do this, so did a lot of people. For over a year, I attended Orthodox services and Lutheran services, but did not commune at either. I wasn't a catechumen yet, but I knew that communing in the Lutheran church would still violate my conscience. This may not be a rule for everyone, but I think one needs to reflect and think about what it is that one is looking for. I was looking for Christ. He wasn't in the Lutheran church the way that He was in the Orthodox Church, in His fullness. If one does not come to the Orthodox Church for the sake of God, then I would question the motive for conversion. People come to the Orthodox Church, but they also, unfortunately for them, leave, even after converting. I think one big reason many leave is because they allowed themselves to be carried along by emotion, without a deep introspection--and, of course, repentance and humility.
