I had my first scan today and was shocked to be told that there was 2 babies! However, one hadn't been growing for the last couple of weeks and only measured 8 weeks but the 2nd twin was measuring 10 weeks. Doctor thought he saw brief flicker of heartbeat on ultrasound but then couldn't find it again and couldn't find it using internal scan. Heartbroken that I may of lost both babies and got to wait 5 days til next scan. Has anyone else not had heartbeat show on ultrasound but baby has been okay?
