refers to the surge of LH and FSH at ovulation. Not only does LH surge to trigger ovulation, but FSH does as well. Interestingly, the standard b/w references show an FSH range for midcycle, but they typically show lower levels than many women really get.
With your E2 level, I tend to think your LH and FSH weren't surging to ovulate, but it is still possible. The E2 peaks just before ovulation and drops when the LH surges. But typically, it would still be higher than what yours is if that was what was happening.
As far as taking something to bring on a period (BCP's or HRT) - that is iffy. For some women, it lowers their FSH and LH and they get a "re-set" of their cycles and things are then more normal for a while. But for some women, it seems to over-suppress their ovaries and their FSH and LH rebound even higher after they stop the BCP's/HRT. So, I understand your reluctance and concerns regarding trying that. It is a gamble. It is something only you can decide. There are some alternatives that women have tried and re-set their cycles, but there doesn't seem to be anything that has worked for everyone. If you do some searches on these boards, you may find some experiences in the past with some of them - wheatgrass, vitex, progesterone cream, etc.
I hope you can get some support from the hormone center.
