Understanding Pregnancy Timeline
The average pregnancy lasts about 40 weeks (280 days) from the first day of the last menstrual period. This calculator helps you track key milestones throughout your pregnancy.
Key Pregnancy Weeks
- Weeks 1-4: Fertilization and early development
- Weeks 5-12: Organ formation and rapid growth
- Weeks 13-28: Baby's systems develop and grow
