The menstrual cycle is divided into two parts: pre-ovulation and post-ovulation. Free Ovulation calculator predicts your ovulation date and fertile days during your menstrual cycle, based on when your last period starte menstrual cycle length and luteal phase length. There are about days during each menstrual cycle when you can get pregnant. Though the length and regularity of a menstrual cycle may differ, the average duration of a complete menstrual cycle is days (though healthy cycles can run from 21-days).
Ovulation happens about days before your period starts. The few days surrounding ovulation (from approximately days to of a 28-day cycle constitute the most fertile phase). The ovarian cycle refers to the cyclical development and expelling of the egg from the ovary.
Our Ovulation Calculator gives you the dates you re most likely to be fertile over the next several months. If your average menstrual cycle is days, you ovulate around day 1 and your most fertile days are days 1 and 14. (If your cycle is days long, your next period should start days from the first day of your last period.).
