Pregnancy & due date calculator
Enter the first day of your last period (or the conception or embryo transfer date) and get the expected due date in the Gregorian and Hijri calendars, how many weeks and days along you are, the trimester, and the key scan dates — which you can add to your calendar.
Everything stays on your phone only
Rounded averages; every baby differs. Your doctor's scan is what counts.
Tap the button for every movement you feel. It stops at 10 and logs how long it took.
10 movements logged ✓
There's no set number of normal movements — what matters is your baby's own pattern. If movements slow down or change, call your hospital straight away; don't wait until tomorrow.
Tap when a contraction starts and again when it ends. It times each one and the gap between them.
Contractions are regular: every 5 minutes or less, a minute each, for about an hour. Call your hospital or go in — unless your doctor told you otherwise.
Go to hospital straight away if your waters break, there's bleeding, constant severe pain, or the baby moves less.
Pack around week 36. Ask your hospital for its list — some provide the baby items.
How to use it
- Pick how to calculate: last period, conception date, or embryo transfer.
- Enter the date (and cycle length if not 28 days).
- See the due date, the current week and the scan dates — and add them to your calendar.
Questions
How is it calculated?
From the first day of the last period we add 280 days (40 weeks), adjusted for cycle length (Naegele's rule). From conception we add 266 days; from embryo transfer, 261 days for a day-5 or 263 for a day-3 embryo.
Is it exact?
It's an estimate — most births happen between weeks 38 and 42, and few on the day itself. A first-trimester scan is more accurate, and your doctor will go by it.
Can I log appointments and kicks?
Yes — below the calculator: the baby's size each week, a kick counter, a contraction timer, appointments with calendar reminders, and the hospital bag. All of it stays on your phone.
Is my data stored?
No, everything stays on your phone.
