Aww, I know it sucks. 3dpo? find anything? lol Google is not our friend!
But I did find this:
Member: Are all cycles different or will I always have poor egg quality? Can fertility medicines cause poor egg quality?

Dr. Amos: Not all cycles have the same egg quality. You are sometimes lucky to get a 'good' egg.

Member: When is ovulation considered late?

Dr. Amos: Most doctors consider ovulation 'late' when it happens after CD 21. Many women do get pregnant with late ovulations, but chances of getting pregnant are decreased. For one, the egg is not as good when you ovulate later in the cycle. A 'not good' egg is less likely to be fertilized and become an embryo. In addition, the lining of the uterus, the endometrium, is where the fertilized egg, the blastocyst, has to attach and implant. If the endometrium is too old, it is less likely to provide sufficient nutrition for the blastocyst, so implantation is decreased. And finally, with 'late ovulation,' you ovulate less often than with earlier ovulation.
