I think, don't make any decisions right now while you're still all caught up in the emotions and momentum of "maybe I am, oh no, I'm not." Let those feelings settle a bit and then see how you feel about it.
Also, and I'm really the last person who should be saying this given my typical levels of control, but I think it would really be better to try and get an A1c at least in the 6s before trying. I understand that the feeling of wanting a baby is extremely strong and overpowering, but I think this is a case where your head really has to win out over your heart. I know it's hard with work and everything too. Again, I'm the last person who should be saying this, because I know this but don't actually do it: I find that the times when I want to say it's impossible to control my blood sugar so why bother, are exactly the times I need to do more. I tend to test less often when life is crazy because it feels like I don't have time or there's nothing I can do because things are crazy. But in reality I should test and adjust MORE in times like that and I would have a finer control over things.
Like I said, my own control is usually not very good and could probably be better if I put the time into it, but I often feel I don't have the time. On the other hand when I decide I don't have the time, that's a decision I'm making that basically only affects me. I think with a baby on board, or just in mind, it becomes easier to do stuff that you wouldn't otherwise do, because you feel responsible for another being and it's not just your own body at stake. Think of waiting to get your A1c lower as already starting to love your baby before it even exists
I like Patti's idea of giving yourself til the wedding! Not because I'm particularly traditional or anything but I think it makes a nice sort of "deadline," not too far off so it doesn't seem like you're postponing it indefinitely, but far enough that you can start thinking of your BGs in terms of "baby planning" and be ready! Think how much better you'll feel about things knowing you gave your baby the best start you could manage
