Progesterone Cream?

I’d love to hear anyone’s thoughts on and or experience with progesterone cream!

Been TTC about 6 months, and consistently BD around the fertile window. I was starting to think implantation may be part of the issue and not just fertilization. I think that my luteal phase is right on the border of 10 days, and after doing some research online it said that progesterone cream may be helpful.

I am already 3DPO, am I too late to use it this cycle? Has anyone actually had success with it?

Thank you!!
