Progesterone

Tia • Married💍 TTC baby #1 for 3 years- 1 MC

I recently had a miscarriage and actually just found out today. My doctor wants to start me on progesterone for my periods because before I got pregnant I only had one every 3/4 months. Does this help with TTC at all or just the period starting back up? Do you ovulate taking this or not?
