Adjust for Cycle Length: If the catamenial cycle is not the standard 28 days, adjustments may be necessary. for representative, if the cycle is 30 days, subtract 2 days from the 280 day count.

Note: This method assumes a regular catamenial cycle. Irregular cycles may require additional methods, such as ultrasound, for accurate dating.
