Progesterone levels low

Hey, everyone on Sunday I started light spotting and on Monday it got worse. I found out my progesterone levels were very low. I went in today to get more labs. I found out I miscarried. My husband and I are heartbroken. I was 6 weeks and 5 days. I have to go back in to check again. Does anyone know what I can do in the future to help my progesterone levels or does it very each time. We are hoping to try again soon.
