Implantation typically occurs 6 to 10 days after ovulation, or day 20 to 24 of a menstrual cycle. However, it can happen a few days earlier or later. In an average 28-day cycle, ovulation occurs on day 14 with the first day of a woman's period being considered day 1 in a cycle.
Anyway, it could start 3 days after a 3-day transfer, or the day after a 5-day transfer, depending from woman to woman. You can have menstrual-like cramping and bleeding during implantation, which is common symptom. However, often it is a silent process and most women do not experience cramps before implantation. I am telling you this although I am not a doctor, because I had long time until I finally get pregnant.
