Congrats hun This will be your biggest maintenance challenge ever. I went through the same (7 years maintaining before pregnancy). I'm back to where I was before, in maintenance. While it's hard to gain after all that hard work, you will also gain a great new reason to stay healthy. Your lifestyle impacts much more than yourself now. Enjoy your 9 months and have fun with it
