Hi Kelly Sue,
Wow, that's good news!
Personally, I wouldn't panic. You will need all your energy when the baby will arrive, don't exhaust yourself! I think pumping every 2 hour is good (it's what newborns do - nurse every 2-3 hours). Be confident in yourself, and prepared... do you have a supplementer? You may need it while your supply is building.
Good luck, and have a wonderful new life with your new baby!
