One day at a time, mama. :) That's still the best advice no matter what. You have a heartbeat, YAY! And do you know how many people would trade to be in your shoes in regards to the weight issue?! It never comes on or off when they say it will, the standard info is just a generalization.
I know it's difficult to control the anxiety when we're a bag of hormones, but just take a deep breath, and focus on your little ones. :)
Good luck!
