38 eggs retrieved...

So I had my egg retrieval this morning and embryologist said I have 38 eggs. I was really surprised and quite worried because Ive read that the quality of eggs goes down after 20 eggs. Not sure if this is just at a certain age, for fresh embryo transfer or if it's for frozen as well but I am so concerned that my eggs won't be quality and that my frozen embryo transfer in January will miscarry due to how many eggs were retrieved during egg retrieval. Can anyone give me some insight on this cause I am so concerned and stressing out about it.
