It is not typical to get 15 eggs with an AFC of 5.
Original poster: what was your cd3 FSH this month? Will your RE cancel you if you don't get 5 follies? There are different extremes of DOR and you may need a doctor who will retrieve with less. At 29 your eggs, even if low in count, should be decent quality. You just need to get them out and test them out. I have never made 5 eggs. I was retrieved 4 times. My quality was terrible but I'd never know that if I was always cancelled. Waiting one more month at your age is fine but it is doubtful that you will get a ton of eggs on any given month. With the added OOP cost, you can't keep shelling out tons of money on drugs to get cancelled every time. If you can't get your RE to retrieve unless you have "X" eggs, I'd find another doctor who will. They are out there.
