I have PCOS with very very long cycles. My first cycle off BC (a year ago) was over 100+ days and I was then prescribed progesterone to induce my period. I took it for 10 days and then got my period exactly 14 days later (which is the "limit" my doc said before calling him). Then my next cycle was 150+ days and I got progesterone again (also metformin) and took it for 10 days and my period came about 3 days later (much quicker this time).

Now I'm not waiting as long to get the progesterone, i had one "natural" period after a 38 day cycle (woo!) but this one wasn't so lucky. I got a prescription for progesterone again on day 43 because i wanted to jump start my cycle (not wait over 100 days) and do Clomid for the first time next cycle. The problem is, I took the progesterone for 10 days and it has now been 17 days since i finished it and no period in sight.

Has anyone taken progesterone and not gotten a period within 2 weeks? I've left a message with my doc, but haven't heard back yet.
