Pregnancy Due Date Calculator
Pregnancy Due Date Calculator?
How A Pregnancy Due Date Calculator Works? A Pregnancy Due Date Calculator is a nice online tool that calculates when your baby should be due based on some key factors including:
- LMP (last menstrual period)
- Length of your cycle on average
- Conception date (if known)
- Date of ovulation or IVF transfer (for those using assisted pregnancies)
An expected due date is based on the day of the last menstrual period (LMP). A calendar that can predict your future, such as Naegele's Rule, typically indicates you are 40 weeks from your LMP.
How Does Pregnancy Due Date Calculator Work?
The vast majority of calculators execute in this simple way,
- You input your data
- LMP date
- Duration of cycle (classically 28 days)
- Conception or ovulation date (optional)
- It applies pregnancy dating rules
- This is 280 days (or 40 weeks) after your LMP
- Adapts to different cycle or IVF schedules
- A custom timeline to your pregnancy
- Due date
- Current pregnancy week
- Trimester breakdown
- Key prenatal milestones
Why use Pregnancy Due Date Calculator?

- Improve prenatal care planning.
- Assist in scheduling necessary testing and ultrasounds.

Yes. Because early ultrasounds can provide a more accurate due date, particularly if your menstrual cycle is irregular or you are unsure of the conception date,
