Progesterone deficiency? Treatments?

Melissa

I have been trying to conceive for 14 months now and yesterday my gp told me I may have progesterone deficiency (or I may just ovulate late) according to my 21 day bloodwork. Wondering if anyone has been diagnosed with progesterone deficiency and a) what the treatment was, and b) have you since been able to conceive? And c) how long it took?

Thank you for any responses :)
