Have intercourse on "high" and "peak" fertility days.
1. |
Fertility BEGINS on day 6 of the first 6 cycles. |
2. |
After 6 cycles, fertility BEGINS on the earliest day of "peak" during the last 6 cycles minus 6 days or the first "high" reading on the monitor - whichever comes first. |
3. |
Fertility ENDS on the last "peak" day on the monitor plus 3 full days. |
4. |
After 6 cycles, fertility ENDS on the last "peak" day of the last 6 cycles plus 3 full days, or the last "peak" day on the monitor plus a count of 3 full days - whichever comes first. |
These instructions are to be used only for those women who have cycles between 22 and 42 days in length. If there are two or more cycles that fall out of that range or the menstrual cycles vary by more than 10 days, see your professional NFP teacher for advice.
Women who are coming off of hormonal contraception, who recently were pregnant, or who recently stopped breastfeeding should wait until they have at least 2 natural menstrual cycles in a row before using the monitor. There is a separate protocol being developed for women who are breastfeeding and not in cycles.
