If anyone has had a six week scan can you show or tell me what you seen. I seen a heart beat when they done a internal scan, but it's right at the top tucked up and I couldn't see a yolk sac but the heart was beating. I know you have to have a yolk sac to have a baby and heart beat but I couldn't see it. Basically I'm just worried. The lovely ladies who done the scan said it looked like a happy and healthy pregnancy and they gave me a picture...but I struggled to see what they were seeing and I left really worried...
