On strike

My body that is, for some unknown reason last cycle was of normal healthy length. This time.... Day 22 and still waiting to O. At this rate I will still be on the same cycle when I go back to the specialist at the End of Feb. This is making things tough. No matter how much I want my body to behave, it is just not happening. I mean I could try Vitex or just start provera on day28 if there is no O in sight, but it is the whole let down my body is giving me.
