Great to hear from you! I want to extend my sympathies , I'm sorry about the miscarriage, how awful. I have had on too, years ago, it was very difficult for me. However, Its great that you guys are trying again :)
I too have certainly had ups in downs, I've put on a majority of the weight I've lost, and I'm starting back on Monday again with diet. Trying exercise, but was in a car accident which injured my back, so it's really hard to get exercise in without pain unfortunately, but I'm slowly getting better.
When you get into a tight place and everything goes against you, till it seems as though you could not hold on a minute longer, never give up then, for that is just the place and time that the tide will turn!
