Low Progesterone- HBU?

I got my first round of labs back. They didn't say my AMH was in danger but I have "slightly low progesterone". AF started today (I am excited about this), so on Sunday I'm getting my thyroid, testosterone and a few other labs drawn. On Wednesday I am getting my pelvic ultrasound. After this is all completed, I will know what the journey is going to look like. How are things ladies?
