Have any of you ladies taken progestrone alone without taking clomid or letrozole as well and had luck conceiving just with progestrone? Last month I took clomid 100mg n progestrone conceived but had chemical next month we decided to hold off on clomid n just do progestrone well yesterday was last day took test n got a BFN so maybe clomid does help but he going to get himself checked so that's why I holding on treatment for me?
