Just pointing out a small technicality since I don't know the OP. I'm assuming she's here on a spousal visa, in which case it's right, but there are some visas (especially visitors and such) that wouldn't be able to access any of that even while pregnant. I'm quite sure this isn't a problem, but just saying anyway . . .
It's a nice thing isn't it? I've managed to get some good dental around LO's birth that I couldn't have afforded. Now I'm nervous because they are saying I'll be needing my first root canals and crowns, but they can't do it yet without x-rays b/c of my pregnancy, so I'm having to wait till the baby comes and hope for the best in the meantime. So a month or two from now, I may not be such a happy camper.
