Myndi mentioned in her comment on my last post that her oestradiol had been elevated on one cycle because of a cyst. I've been thinking about that and looking back at what happened in my previous cycles, and I think she may be onto something.
The doctor who scanned me didn't mention the word 'cyst'. But on each ovary, the thing that was there was 14mm - and surely that's too big for a normal follicle on day 2. The cyst that I had in September was 17mm, and on IVF#1, after five days of stimming at a very high dose, my biggest follicles were 14mm and Nurse Perfect was saying I was almost ready to trigger.
So I'm pretty sure that I have at least one cyst, and probably two. And since these cysts are caused by a failure in ovulation, perhaps that explains why I had no ovulation pain last cycle, as I usually do.
If that's the explanation for my high oestradiol, then I'm fairly comfortable that it ought to come back down in the next one or two cycles - and if I can just keep my FSH down as well, then we should be going ahead soon. So I'm now thinking cyst-deflating thoughts, just in case...
