How late in ones cycle can ovulation occur?
Hi, In most healthy, fertile women, the shortest their luteal phase will be is 10 days (this is the time from ovulation until you get your period) and the longest is 16 days. It is usually closer to 12-14 days. So, for example, a woman with a “normal” 30 day cycle could ovulate anywhere from CD14 to CD20. Likewise, a “normal” 35 day cycle could mean ovulation anywhere frm CD19 to CD25. This is why fertility charting is so important. Even though every woman’s luteal phase is different, most women have the same length LP from cycle to cycle (it’s the follicular – or pre-ovulatory – phase that can fluctuate). If you chart your BBT (waking temperature) every morning, you will be able to tell when you ovulated by a sustained rise in your temperature by about .4 degrees F. You may ovulate on a slightly different day each cycle, but you will see that once you have ovulated it is always the same number of days from your ovulation day until your period (plus or minus a day every once-in-a-while
