1,2 or 3?!

3 seperate sacs, one they could see a small baby in with a heart beat the other two sacs couldn't see much but they have told me because they would all seperate babies in their own little sacs that there's Is a 50/50 chance on my next scan there could well be 1 2 or 3 babies as because it was an early scan there was still time for the babies to be too small too actually show up?

Anybody been through this and there been more than 1 or would this be a failed multiple pregnancy.
