We're on cycle 8 of ttc #2 and my LP is never longer than 8 days. I had a mmc at 12 weeks before I had DD and both times I didn't have this issue as I was tracking. I've tried b6 complex and it's done nothing, and 21 day progesterone came back at 40 so docs aren't concerned. I'm really starting to lose hope, does anyone have any pearls of wisdom please?
