Simple calculators to help you plan and understand your cycle.
Pregnancy Due Date Calculator
Enter the first day of your last menstrual period (LMP) to get an estimated due date. This is a planning estimate, not a medical diagnosis — your doctor will confirm dating more precisely, usually by ultrasound from around 5–6 weeks.
Ovulation & Fertility Calculator
Enter your average cycle length to estimate your fertile window and likely ovulation day. Useful for planning when to try to conceive — or when a high-sensitivity test like TrueScan® Easy might be worth using.
A Note on These Tools
Both calculators give estimates based on average cycle patterns.Actual ovulation and implantation timing vary from person to person,and irregular cycles will shift these estimates. For the most reliable pregnancy confirmation, test from the first day of a missed period using first-morning urine — and talk to a doctor for anything these tools can’t answer.
