I'm in a similar position to you except my clinic and consultant say it's too early to give up on using my own eggs. I'm about to do my 5th egg collection and here are my results so far, aged 38, AMH 6.
Cycle 1 - NHS, short cycle, 300iu Meriofert, 9 eggs, 5 mature, 1 blast 3BB, BFN.
Cycle 2 - Private clinic, long cycle, 350iu Overleap, 4 eggs, 0 mature, 0 blasts. We decided long cycles were not for me, reverted back to short.
Cycle 3 - Same private clinic, short cycle, 375iu Meriofert and upped to 450iu Meriofert on day 8; 6 eggs, 4 mature, 2 blasts, one 2AB transfer BFN, 1 5AB hatching blast in the freezer. Best cycle.
Opted to do 3 embryo banking collections given low AMH and age.
Cycle 4 - short cycle, 450iu Meriofert, 4 eggs collected, 0 blasts. Conclusion with the consultant was that the high dose of Meriofert although sparked my follicles on my day 5 scan it impacted quality. I was on track for 6-8 eggs to be collected based on follicular graph but only 4 collected and poor quality, only 1 8 cell embryo at day 3.
Cycle 5 - short cycle, 375iu Meriofert upped to 450 iu for the last 3 days. Collection Friday. Based on follicular graph I'm hopefully of 3-5 eggs being collected.
The key thing I've learned is to not expect lots of eggs or follicles with a low AMH. I want to see three large (over 15mm) on my final scan to feel like I'm in with a chance. I aim for 3-5 eggs to get collected and hope for 1 blast per cycle. This helps with my motivation as I'm not being unrealistic.
I was interested to see recommendations for Pergoveris and Gonal F as if this cycle ends in 0 blasts I'm going to be asking to swtich meds as my body is getting too used to Meriofert.
I wish you all the best on your journey and you getting your golden egg.
I'm not giving up yet - I don't think you should either if you can emotionally and financially keep going!
