An ovulation calculator estimates when you're most likely to ovulate based on your menstrual cycle data. Here's how it works:

Standard Method: Assumes a 14-day luteal phase (time between ovulation and next period). Ovulation date = Cycle length - 14 days.

Three-Cycle Average: Provides more accurate results by averaging your last three cycles if data is available.

Custom Luteal Phase: For women with known luteal phase lengths different from 14 days.

For best results, use this calculator along with other fertility awareness methods.

Note: This tool provides estimates only. Individual cycles may vary. Consult a healthcare provider for family planning.
