In regards to the rejoining question....as others have said, you did not have to quit TOPS when you became pregnant. We have a gal in our chapter that has gained only 14#'s with only 5 weeks to go....hey, same as you.
Since you have left, you can go back anytime, even now. There are no rules forbidding pregnant ladies from joining. Only KOPS members need to have a weight gain limit set by their doctor....TOPS do not have to do this and are not limited, but of course, you don't want to gain too much. Yes, your chapter will have to count your gains for the next few weeks, then they get to count all the weight you will lose post baby. They should love that for their year end resume chart!!!! Our chapter is looking forward to our gal having her babe

Glad your looking forward to coming back!!
Congratulations on your bundle-to-be. Have a healthy, happy labor and delivery.
TOPS Hugs,
Summer
