I went for my u/s. (Try scanning picture later even though it's a lousy one). The baby is measuring 7w0d (it was 7w1d since the m/c started so on date perfectly). Heartbeat was beating at 150. I'm expecting a call back from the nurse some time today cause the tech just kept looking and saying hmmm or "that's weird"..But she did say all looks great and asked when my next appointment was. I'm wondering if it was another underdeveloped twin but I couldn't really see.
Either way, she left the baby on the screen and both DH and I were able to sit and watch the heart beating away..
