How to Calculate • D1 (1ST day of menstrual cycle) next menstrual cycle • Normal: 28 days ( 23-36 days) • Fertile D5- D25 To Calculate Fertile phase: subtract 18 from shortest cycle and 11 from the longest * Shortest cycle: 23-18 = 5 (infertile phase) * Longest cycle: 36- 11 = 25 (post-ovulatory infertile phase)
EXAMPLE Bechay 22y/o regular menstrual period LMP: June 15’09 June 29 – ovulation period (add 14) +/- 5 days = SAFE/ NON FERTILE
