depende sa cycle, short ang cycle early ang ovulation, kaya dapat po monitor muna for 6 mos yung cycle nyo, if its 28 to 30 days which is the normal cycle, day 14 ang ovulation nyo. but some women kasi can have 30-35 day cycle.
since October 8 ka dinatnan kunwari ang meanstruation mo October 8 na tapos kunwari 3 days ka lang regla mo ang fertile days mo is October 16
