How the tracker works
Pregnancy is dated from the first day of your last period, not from conception, so at 4 weeks you're only about 2 weeks past conception. Full term is 40 weeks. This tracker counts back from your due date (or forward from your last period) to find your exact week, then shows your baby's size and what's developing. It's an estimate for guidance; your midwife's dating scan is the definitive source.
This tracker provides general educational information only and is not medical advice. Always confirm your dates and any concerns with your midwife or doctor.
