munchkin14 and sorry to hear about your 2 cancellations. Such a big disappointment when it's your main focus and you have invested so much energy and hope in it! For me estrogen was >8000 by day 6 and clinic was not happy to continue. I didn't think it was that high but apparently they never get good results if it climbs that high that early. I'll be on a lower dose this time (100 instead of 150) fingers crossed it works!
