Had an ultrasound today internal one and as soon as the screen came on my husband said is that twins and the sonographer said you've got a good eye. As the scan went on something was visible in the sac on the left but not yet in the sac on the right which made him question if it was a hematoma or a second sac. My friend had twins and her scan looked very similar to mine. Whats other peoples thoughts and opinions? Had bloods done as images were not very clear to determine via pregnancy but we definitely seen a flicker in one sac
