Twins seen in ultrasound, but only one had heart beat

[Maria2707]

I had my first ultrasound on Nov' 19th at 6.6 weeks. We saw twins, Baby A measuring 6.1 weeks and heart beat was  deected. Baby B measuring 5.5weeks and no heart beat only yolk sac. Have to go for another us on 2nd. What are the chances of Baby B catching on? Why was babies measuring only 6.1 and 5.5 weeks. I was 6.6 weeks on the day of ultrasound. Anyone here know or gone through this situation.

I do know a lot can happen in only 1 week where the baby can catch up in growth! Be patient. My thoughts are with you. Hopefully you'll have great news at your next u/s!!
