Welcome to the board!
Hi, LaRae! So sorry to hear about your m/c -- many of us have been there and it's awful.
Since you have had children before and have been pregnant very recently, I think your chances are great. But if you don't get PG again soon, I recommend going to see a reproductive endocrinologist (RE) to find out what's up with your hormones, tubes, etc. At 42, there's not a whole lot of time to fool around, so to speak.
Good luck with everything, and welcome!
LaRae, welcome to the board and congratulations on your upcoming wedding!
