On occasion, a woman will find it difficult to identify her Peak Day, which can happen if she experiences a lot of cervical mucus. The inability to confidently identify a Peak day will delay the important step of obtaining a peri-ovulatory estradiol panel and/or a post-Peak estradiol and progesterone panels, which are necessary in order to allow us to progress through the NaPro diagnostic evaluation process and form an individualized treatment plan.
Most often, your FCP will be able to teach you a CrMS technique called the "Essential Sameness Question" (ESQ), and apply the use of "yellow stamps" (YS), which will almost always solve this problem.
However, on very rare occasions a woman will continue to have difficulty identifying her Peak-day. If this occurs, your NaPro provider can offer you an option to have serial P+3 progesterone levels drawn for a few months, to help you build confidence in your charting. NaPro research has demonstrated the following:
Progesterone Levels to help interpret Peak day:
- 0-1 = you have either not ovulated or you are within 24 hours of starting your period
- 1.1-2.3 = you are just prior to ovulation on in the midst of ovulating. Repeat lab in 24 hours to clarify the situation.
- 2.3-3.0 = you have almost for certain ovulated. Repeat lab in 24 hours to clarify the situation.
- >3.0 = you can be confident that have passed your Peak day.
Most often, after a few months of doing serial P+3 lab draws, the woman will most often be able to confidently identify her Peak day.
