Well, it sounds like you just need to relax. Youve done your home work, just let things flow like they should. It sounds like your ready. I would get a blessing about it if you are still having anxiety about it. And perhaps do some fasting before the blessing.
As far as financially being ready, it would be wise to maby get a small part time job for a baby fund, not a lot but a boost. But, you ll find the way. We have had financial problems ever since we got pregnant, I lost my job and was stuck in the hospital for most of my pregnancy, after Adam was born, we lived in the N.I.C.U. For several mounts and my husband lost fis job not too long after, somehow we have pulled through. God will not give you more than you can Handel. You just have to make good choices with what you have. I know things will work out for you. I would get your hubby going in the church so you can have a strong priesthood holder in your home, and tithing is such a blessing! Always remember that, sometimes I wonder how we will have food for the week when I give my tithing to the bishop. And remember that we still need pull ups too, but with what? And somehow it never fails God gives us so much more than we need its like a miracle!!! God bless.
