Home / Calculators / Early pregnancy / Pregnancy milestones
Every calculator in one place, free and with no sign-up. Results show instantly — we don't hide them behind a form. Each one explains what the number means, where the reference ranges come from, and what it cannot tell you.
A calculator sees three or four figures. A specialist sees your history, your scans, your partner's results, and how you actually responded to treatment. If you're between cycles, changing clinics, or something in your results doesn't add up, a second opinion is the fastest way to find out whether anything would be done differently.
Free first consultation. No obligation to start treatment, and it doesn't affect your care at your current clinic.
These tools provide general information and are not a diagnosis or a substitute for assessment by a qualified clinician. Reference ranges and sources are stated on each calculator. Predictive estimates describe groups of people and cannot predict an individual outcome.

Source — Indicative schedule. Antenatal timetables differ between countries, and between units within a country. Your own maternity plan takes precedence.
The bands on this page are drawn from published sources but have not yet been reviewed by our medical team, and some vary by laboratory or assay. Check against the reference range printed on your own report.
Gestational age
That falls in the first trimester band.
Your result of 8 weeks sits in the highlighted band. Bands are reference points used alongside clinical findings — not a diagnosis.
Early scans confirm location and heartbeat. After IVF the first scan is usually earlier than in a spontaneous pregnancy.

Highlighted is the stage this measurement belongs to. It is a map of the process, not a schedule — timings vary by protocol and by clinic.
The early part usually is. Clinics normally scan at 6 to 8 weeks to confirm location and heartbeat before discharging you to routine maternity care. The rest generally follows the standard pathway.
