About Women’s Health Calculators

These four calculators follow the reproductive journey from cycle to cradle: the period calculator predicts your next dates from cycle length; the ovulation calculator finds your fertile window (ovulation ≈ 14 days before the next period, with a ~6-day fertile window); the gestational age calculator converts your last period into weeks + days and your trimester; and the pregnancy due date calculator applies Naegele’s rule (LMP + 280 days) for your estimated delivery date. They use the same obstetric conventions your gynaecologist uses — but they’re planning aids, not medical care. Confirm everything at your appointments, especially with irregular cycles or PCOS, which is common and treatable.

FAQ

How accurate are these for irregular cycles?

Less so — the formulas assume a known, roughly regular cycle. With PCOS or irregular cycles, treat them as rough guides and rely on your doctor’s scans.

Which calculator do I use when?

Trying to conceive: ovulation. Pregnant: gestational age + due date. Planning ahead: period. They chain together naturally.

Do these replace antenatal visits?

Never. Dating scans, anomaly scans, and glucose tests are scheduled by gestational age — the calculators help you understand the schedule, not skip it.
