does the luteal phase ever change
Report Abuse. It's usually pretty consistent, but it can vary from month to month depending on when you ovulate. For example, you can have a 28 day cycle and ovulate one month on CD 14 with a luteal phase of 14 days.But next month you may ovulate a couple of days later, on CD 16 with a luteal phase of 12 days. They're both regular, normal periods with normal luteal phases and ovulation periods, just at different times.f you typically ovulate on cd 16 and have a 12 day luteal phase, you will have a 28 day cycle. With ovulation on cd 14 with a 12 day LP, you will have a 26 day cycle. Good luck and baby dust :). Source(s): ttc #1 for 2+ years.
