Don’t women ovulate on the 14th day after their period starts?
Unfortunately this is a myth that many still hold on to, including healthcare professionals. The day of ovulation differs from woman to woman and can even be different from month to month. The “14th day” thinking appears to come from either taking the average of when all women ovulate or from someone just dividing the 28 day cycle in half. However this myth got started, it is not an accurate way to calculate ovulation, because many women do NOT ovulate on the 14th day of their cycle.
