After ovulation, the egg is released from the ovary and enters the fallopian tube. This is a crucial moment in the menstrual cycle, as it marks the time when the egg is available for fertilization by sperm. The fallopian tube is the site where fertilization typically occurs, provided that sperm are present. The egg will begin its journey through the tube toward the uterus, where it can either implant if fertilized or be expelled if not.

During ovulation, the body prepares for potential pregnancy. Choices like the beginning of the menstrual phase and implantation refer to processes that occur at different times in the cycle. The menstrual phase starts only if fertilization and implantation do not occur. Fertilization happens in the fallopian tube, but it is not an immediate result of ovulation; thus, the egg is first traveling through the fallopian tube after being released.
