Did you wait for testing?

Michelle🐶 • 8 angel babies, now divorced but still hopeful for my first human child - already have my pitbull fur baby!!
I'm going through my 3rd MC and my doc has given me a referral for a specialist for bloodwork and to check on everything. (Clotting disorder, chromosome issues, etc). I called, and they don't have any openings until mid January and even then 10 people are ahead of me. I know some of the results take weeks so I'm thinking I won't know until April at that point. 
Has anyone been in this situation? Did you want to try for the work up or just keep going in between?
