Calling all twin pregnancies for Dec!! Where are you?

Mo
I would like to have some friends that are going through this together. I have already had two prior pregnancies they are 8 & 9 years old my boy is the oldest and my girl is the youngest. With this twin pregnancy I will not be finding out what I am having unless.... It just happens. Or deemed necessary.  So far, I had an US and found two babies. Baby B has a heart rate of 141 we couldn't find Baby A  heartbeat so I am following up this Thursday. I am so nervous. I am 7 weeks and 5 days.
