Just found out today I'm got twins had with a scan and They Discuverd 2 separate sacs each containing A yolk Sac but only one has A Detected heart beat any body know what the chances are Of the one without the heart beat being OK, got to go back in one week for another scan.

I don't have an answer for you question but all I want to say is Congratulations for your pregnancy and I hope everything goes well. I'll pray that both your Babies will be safe.
Good Luck :)

I am afraid I don't know much in the department of twins. However, it could just be so early in the pregnancy, that it was hard to see the other heartbeat? I hope that you find out good news at your next appointment, and congratulations of becoming a mommy. Best of wishes, and keep us updated
