Hi I had a scan last week at 5 weeks 4 days pregnant, there was 2 yolk sacs un the one gestational sac? I asked the woman who done scan what it meant and she said I'll have to go back in 2 weeks for re scan, could it be teins? I'm confused!! Have my scan on 21st jan, can't stop googling it and different things coming up? Has anyone had 2 yolks in 1 sac before and was twins? Thanks for reading xx
