Current Gestational Week
12 weeks
Current Gestational Week vs Days Since Last Period Started
Formel
## Naegele's Rule The estimated due date is 280 days (40 weeks) from the first day of the last menstrual period (LMP). **Due Date = LMP + 280 days** ### Trimester Breakdown | Trimester | Weeks | |---|---| | First | 1-12 | | Second | 13-27 | | Third | 28-40 | Only about 5% of babies are born on their exact due date. Most arrive within 2 weeks of the estimate.
Lösungsbeispiel
A woman whose last period started 84 days ago.
- 01Gestational week = floor(84 / 7) = 12 weeks
- 02Extra days = 84 - 12 x 7 = 0
- 03Days remaining = 280 - 84 = 196 days
- 04Weeks remaining = 196 / 7 = 28.0 weeks
Häufig Gestellte Fragen
How accurate is the due date?
Naegele's rule is an estimate. About 80% of babies are born between 38 and 42 weeks. An early ultrasound can refine the estimate.
What if my cycles are not 28 days?
Naegele's rule assumes a 28-day cycle with ovulation on day 14. If your cycles are longer or shorter, the due date may shift accordingly.
When is each trimester?
First trimester: weeks 1-12. Second trimester: weeks 13-27. Third trimester: weeks 28-40.
