Twins can be detected on an ultrasound at 5 weeks, but it's not always guaranteed. At this early stage, the ultrasound may show two gestational sacs, signaling a twin pregnancy. However, visibility depends on the scan's quality and the technician's expertise. Sometimes, one embryo may be hidden or not developed enough to be seen. A follow-up ultrasound is often recommended to confirm a twin pregnancy definitively.
