Long cycles post miscarriage

Feeling so frustrated. I had my daughter in Dec 2016, and we’ve been TTC baby 2 since June. I’ve been tracking my bbt since my miscarriage at the end of July. I have had two longer cycles since my period returned at the beginning of September.

My most recent Cycle is below. I’m on day 39 with no period in sight. I’ve had some heavy cramping, but no bleeding. Im pretty sure it’s an anovulatory cycle. 🤷🏼‍♀️ but don’t know what to do to make my period come?!? I’ve taken a few pregnancy tests, all have been negative.

I called my doctors office and requested tests to hopefully find some answers. They ran a thyroid test today, but I have to go to a different lab for any genetic testing. Am I missing anything I should be asking for? I’m 33 & don’t want to wait too long for

Interventions if that’s the route I need to take?
