Hi BW - nothing so far has suggested PCOS but I do seem to have very odd drug responses. The last two cycles, I did a long down reg, starting on 150u puregon. First cycle, borderline OHSS, second cycle - v little response, even after Puregon was bumped up to 250. This cycle was a microdose flare with 300u Puregon (which I did think was quite a big starting dose for me) and I go crazy. My FS took me off Puregon on Tuesday and has coasted me for a few days which has brought my E2 down to 12000 with trigger yesterday. I honestly think he is very curious as to what is going on as he has never seen fully sized follicles after 5 days of stims. I can't see how I could possibly have any mature eggs after that short amount of time and am fully expecting no eggs at EPU tomorrow. However, if they do drain all the follies tomorrow, even if there is nothing there, that doesn't mean I am out of the woods with the overstimming, though, does it?
I have really been having second thoughts as to whether or not we should have agreed to an EPU. The more I think about it, the more I think perhaps we should have just bitten the bullet and cancelled because now I am super stressed about tomorrow and the next few days.
What other pointers towards PCOS are there? I have had testerone etc done and all was normal, it has never been brought up at scans and I am normal size.

Josie - awesome egg haul chick. Hoping you are feeling better and there are some beautiful looking embies for you. Tentative, experimental EPU for me tomorrow - time will tell what will be found! Good luck!
