Progestrone suppositories


Has anyone needed to take progestrone suppositories? I had 3 miscarriages prior to this, and honestly this was a suprise considering how close it was to the last time I miscarried. My Dr put me on the suppositiores immediately, still waiting to get blood work to confirm my numbers are increasing.. but I am a nervous reck and my boobs are killing me! Im hoping this is just a side effect to the suppositories.. anyone experience this?
