Hi - I had a successful IVF cycle 3 years ago when I was 38 and am now doing another one at age 41. My FSH is <5 and i was put on the down-reg protocol as that is what worked for me last time. however, things have been going not so well. I started lupron 12 days ago and when i got my period, about 7 days in, i went in for BW/and ultrasound - but was told to not start stims as my estrogen was 120. they told me to wait another 5 days and come in today for BW and US and again, estrogen was too high - 125. Now they want me to up the dose of lupron to 20 units, from 10, and come in for more BW/US on Sunday. They looked closely and said I definitely do not have a cyst and had 11 small follicles on one side and 15 small on the other. What could be the cause of this? This never happened when I did it before (had 3 prior ivf cycles). Is it because of my advanced maternal age? Should I be considering a different protocol? Any advice would be much appreciated....

thanks!
