AFC 20, retrieved eggs 6

Dear all, I just had my fourth ER with a new clinic. I turned 40 a couple of days ago. My AMH is between 0.85 and 1.1, FSH 6.7.

I had an AFC of 20 this time (scan cycle day 2), on cycle day 6 they only saw 4 follicles and they retrieved 6 oocytes after 12 days of stimulation.

I've never had such a big drop before? Two out of three times I even got more oocytes than the AFC.

Has anyone experienced a similar situation?

Normal antagonist protocol, cold start on CD 3, 225 gonal f and 75 Meriofert, as of day 6 orgalutran/ ganirelix and double trigger with ovitrelle and decapeptyl 0.2.

Thanks so much for reading.
