With an FSH of 89 and estrogen < 10, your estrogen is very low and likely has been for possibly months (based on FSH 89). With this low of a level, your lining should not have built up much or at all hence little to nothing to shed. And progesterone helps to keep it from building up. However, it can take as long as 10 days or so after stopping the progesterone to trigger a bleed. But I suspect you won't see much of a bleed with these low estrogen levels.
I'm curious if you are having menopausal symptoms with such a low blood level?
