Can you know when your egg is fertilized?

No, it's not possible to know when an egg is fertilized. Fertilization occurs when a sperm cell penetrates an egg cell, leading to the formation of a zygote. This process usually happens within a few hours after ovulation, which occurs when a mature egg is released from the ovary. However, it can take several days for the fertilized egg to travel down the fallopian tube and implant into the lining of the uterus, a process known as implantation. Therefore, it's not possible to determine the exact moment of fertilization or know when the egg is fertilized until implantation has occurred and pregnancy hormones start to be produced.
