3 DPO: what is happening to your body?
When you ovulate, you’re beginning the luteal phase of your menstrual cycle. This phase continues until you get your period or a fertilized egg implants in the uterine lining. At 3 DPO, a mature egg has been released by the ovary and has traveled through the uterine tube. An egg typically stays in the uterine tube for the first 12–24 hours after being released by the ovary until it’s either fertilized or reduced. This is why there is a short window for fertilization.
