How Our Calculator Works
Understanding pregnancy due date calculations
Last Menstrual Period (LMP)
The most common method adds 280 days (40 weeks) to the first day of your last menstrual period. This assumes a 28-day cycle with ovulation on day 14. We adjust for different cycle lengths.
Conception Date
If you know when conception occurred, we add 266 days (38 weeks) to estimate your due date. This method is more accurate for women who track ovulation or have irregular cycles.
IVF Transfer Date
For IVF pregnancies, we calculate based on the transfer date: Day 3 transfer + 263 days, or Day 5 transfer + 261 days for the most accurate results.
Important Pregnancy Milestones
Track your baby's development week by week throughout your pregnancy journey
Heartbeat Begins
Your baby's heart starts beating around week 5-6. This tiny heartbeat can be detected via ultrasound, marking an exciting first milestone.
End of First Trimester
All major organs have formed. The risk of miscarriage drops significantly. Many parents choose to announce their pregnancy at this stage.
Feel Baby Move
First movements (quickening) are felt, usually between 16-22 weeks. These gentle flutters soon become recognizable kicks and rolls.
Anatomy Scan
Detailed mid-pregnancy ultrasound checks baby's development. Gender can often be revealed if parents wish to know.
Third Trimester
Final stretch begins! Baby's brain develops rapidly, and they start to regulate their own body temperature.
Full Term
Baby is fully developed and ready for birth. Most babies are born between 37-42 weeks. The big day is near!
