6w4d ultrasound and 7w4d ultrasound

Well I got back from my ultrasound and everything looks great! The babies are measuring 7w5d (one day ahead) and their heartbeats were 155 and 161! They doubled in size since last week! It was nuts seeing them so much bigger! The top picture is from last weeks ultrasound and the bottom is from today! Can you believe how much bigger they are???!!!
