The way to calculate is that mark the first day of your last period on the calendar. Then mark the
first day of your current period. Then count days between two marks. Subtract 18 from the total
numbers of days in that cycle. Count that number from day 1 of current cycle and that day is
your first fertile day.

period is 11, the menstrual cycle is 28 days long. Subtract 18 from 28 and you will get 10. Then

your first fertile day will be 20. Hence, if Lydia ladies want to have intimacy after 20, Lydia ladies
need to use barrier like condom for intimacy.)
