Progesterone

Elizabeth • 28 year old, happily married! Two miscarriages within 8 months. Praying for our Rainbow baby*
At my first doctors appointment today I was prescribed Progesterone Micronized capsules to be inserted vaginally twice a day and a baby Aspirin daily. High hopes this will lead to a healthy 9 months! 
Has anyone else used these? Any comments on the progesterone?...
