Question: how long after ovulation does a fertilized egg implant?
Answer: When an egg is fertilized, it implants in the uterine lining. This usually occurs between 6 and 12 days after ovulation and about 5 to 6 days after fertilization. Once implanted, the embryo secretes hormones, including human chorionic gonadotropin (hCG), which signals to the mother's body that she is pregnant.
