Hi, I think I regularly ovulate on Day 12 or 13. Can anyone tell me if this is too early or likely to be cause of two miscarriages (e.g. if uterine lining is too thin)?

I’m seeing a fertility specialist but she didn’t even mention testing progesterone or anything about my cycle- just said she didn’t recommend ovulation testing kits. I feel like I’m paying this person so much money and I don’t trust them to do a thorough job! She is testing for blood clotting disorders and autoimmune conditions only.
