What should I expect from my doctor?

I've had 3 miscarriages in the last 12 months. I've been with the same OB for all of them. At what point should I expect my doctor to start recommending things or doing some real investigation?

After the second one, we did one "fertility" blood screening, but everything came back "normal". I just got past my 3rd, less than 2 weeks ago. My progesterone was slightly low after we realized that this baby had stopped developing. But my doctor didn't seem to think that was an issue. The last thing they followed up with on a call last week was, "Let's just wait and see. After your next cycle, you're free to try again." That feels so inadequate considering the previous losses. I'm also realizing there has been zero follow-up for mental health screening.

When did your doctor start recommending more investigative testing, or when did you reach out to a specialist? or change OB's?

Vent: I'm not understanding how we are accepting that women go through the things I'm reading on this thread just to be told to keep trying and hope it goes better the next time.
