Progesterone & Blighted ovum?

I am experiencing my 2nd MC right now due to blighted ovum. Several kind ladies on Glow have suggested next time (if there is a next time)that I begin progesterone therapy the minute I get a BFP. I'm curious to talk to other women who've had similar problems and it's worked for them. I'm 43 & have had healthy pregnancies when I was younger, but things have apparently changed. I also have fibroids. Thanks.
