Suspecting twins? When will you know? People typically discover they're having twins during a routine scan, often in the first trimester. Ultrasound is almost foolproof at diagnosing twins, but the greater the number of babies, the less accurate the ability to detect how many there are. It's possible to see twins (or more) on a scan at around six weeks, though one baby may be missed at this early stage. Sometimes a heartbeat is seen in one sac, but not in the other. Rescanning in a week or two may reveal a second heartbeat, or the scan may show that one sac is growing and the other still empty.

- In brief: About 4 days. Early transvaginal ultrasound for pregnancy is accurate to about 3-4 days. The time for accuracy is from about 6 weeks to 12 weeks gestation. We count from the first day of the last menses for OB dating. We can see the pregnancy before 6 weeks but usually just the sac and adding the fetal pole makes things a bit more accurate.
