Hi I had my 1st scan today and I am 6weeks and 3days..2babies were found only one with a heartbeat the other no heartbeat n clearly smaller..also I have bled only very lightly twice in the past week or two, the doctor has asked me to return for another scan in two weeks time sayin there is a chance the second twin could 'catch up' and be ok!! Is this a possibility or should I not get my hopes up??? I'm so confused thanks
