What this estimate means
Early pregnancy dates are ranges, not exact points. Cycle length and ovulation timing vary, so estimates can shift—especially after the first ultrasound.
This tool gives a clear starting point, not a definitive date.
Early milestones (approximate)
- Weeks 3–4: implantation window
- Weeks 5–6: first heartbeat may be detectable
- Weeks 7–9: first ultrasound often scheduled
Private by design
- No accounts
- No tracking or analytics
- No data stored or sent

How pregnancy dating works
Dating from the first day of your last period assumes ovulation about two weeks later; real ovulation moves with cycle length. Providers often refine dates after an ultrasound.
What this doesn’t mean
This is not medical advice or a diagnosis, and it does not replace your clinician. For questions about your pregnancy, speak with a healthcare provider.
