Double Trouble?

I had an appointment with the doctor yesterday and we were able to hear the heartbeat for the first time. We were then able to hear the second heartbeat. Yeah the doctor scared me for a minute too after a quick ultra sound it was thankfully determined that the "second heartbeat" we heard we only the cord pulse. On a less scary note I felt the little bug for the first time on Tuesday. It was quite a little jump he gave me, but such a fun feeling to have. (No we dont know it is a "he" but that is what my guess is so until furthur notice that is what we will call him)
