Can you start getting pregnancy symptoms 3 days after ovulation?

While implantation of a fertilized egg into the uterine lining (a key event leading to pregnancy) can occur around 6-12 days after ovulation, it's unlikely to experience noticeable pregnancy symptoms as early as 3 days after ovulation. Most early pregnancy symptoms, such as missed periods, breast tenderness, nausea, and fatigue, tend to appear a few weeks after implantation. The exact timing of symptom onset can vary widely from person to person.
