Heartbeat!

Heartbeat! u make me feel so weak! Who sang that song? We heard the baby's heartbeat today. It was just like in Alias when Sydney Bristow was pregnant. Actually it sounded like at the end of Raiders of the Lost Ark when they lock the ark in a crate. Woouwww...woouuwwww...wouuuwww. However it sounded it was music to my ears. It was beating so fast. Like a hummingbird at least that's what I remember from those national geographic documentaries :)
