Is implantation of embryo possible with endometrial thickness of 6mm and carry pregnancy safely?

Rare: There are very few pregnancies that occur when the lining is less than 8 mm thick. That is a very important part of becoming pregnant. The only time i would perform a transfer in that situation is after a full uterine evaluation and with no choice. It is possible to become pregnant, but6 in my experience regardless of age or embryo quality pregnancy rates would be less than 5%.
