Starting progesterone... Any pointers!

I have had recurring miscarriages and although my non pregnant progesterone levels are good, my Dr suggested I start twice daily progesterone suppositories after ovulating. Hopefully this will help sustain things when I get pregnant again. I have no known health issues but was curious for any advice/experience/Feedback from women on progesterone while ttc. I have read mixed reviews online about. This line of treatment. Thanks!
