Hi

When I was TTC I was on progesterone support (pessaries) to lengthen my luteal phase. This was to give any egg (if there was one) the best possible chance to implant etc. In my case it worked and am now pg. Still continuing with progesterone support (now injections) to ensure that I make it through my first trimester.

I would recommend that you discuss this with your FS especially if you luteal phase is a little short.

Good luck
