Question: can you have implantation bleeding on cycle day 29?
Answer: A fertilized egg typically implants about 10 days after ovulation, Dr. Dardik says. "So, on a 28-day cycle, you would ovulate on day 14, implant on day 24, and skip your period on day 28," she says. That is, it could be implantation bleeding if it's happening a few days before you expect to get your period.
