What to expect

Hi all. We lost our baby back in September and have been trying ever since. I know in the grand scheme of things it's not that long, however, my body is not the same and it seems I'm not ovulating consistently so I'm going in for initial lab work today. My doc hasn't expanded on what kind of testing he's looking to do and I'm wondering if any of you have experience and can tell me what might be in the future?
