The fertile time of the cycle coincides with when the egg has been released from the ovary and it is sitting within the end portion of the Fallopian tube. This is usually around 2 weeks before the start of the next menstrual bleed. This means that for a typical 28-day cycle, the fertile time is around 14 days after the bleed started (Day 14). The fertile time will differ depending on cycle length. For instance, for a 32-day cycle, the fertile time is around Day 18. The fertile time, and a couple days either side of it, are the best times for having sexual intercourse in order to optimise the chances of becoming pregnant.
