I've heard very good things about Inositol & Choline however I'm on the fence (doing more research) on whether or not I'd be able to take either as I have a Clotting disorder and I've heard mixed reviews on what it might do to platelets.
But Inositol & Choline are supposedly very good for egg health and A LOT of women with PCOS take it. Maca has in the past regulated my cycles, and have just added it to the mix again.
ETA: I'm very sorry for your losses, I just noticed in your sig that your most recent loss was in Dec. Mine was also a MMC in 12/15 (bleeding began on 12/21).
