Glad you survived your first day back @willow1981, it is completely up to you who you tell and who you don't. Your miscarriage, your rules.
Sorry @HopeSpringsEternal123 can't help you there, I never went down the private testing route. I totally understand why you want to make sure there's nothing more you can do before you try again, I hope whether you do or don't go down this route, you'll find peace of mind.
Be thinking of you tomorrow @Maybepossibly22, hoping tomorrow is the start of your recovery from this time xx
