5 retrieved 4 matured and fertilized

So I got the message today that 4 of the 5 eggs retrieved yesterday were mature enough to be fertilized. Now the waiting period of days 5-7 to see if the cells are doing what they are suppose to be doing. Once that is done, off they go to genetic testing. I’m super nervous that those 4 eggs are not going to be viable when they come back. Im 42, turning 43 in September. I’m not sure if my eggs are healthy enough. Any success stories out there with similar story line. Btw I do have a 7 year old who I had naturally with my ex. I want to have a baby so bad with my current husband. He treats my little girl so well and I know he would be an amazing father...
