Lots of movement!

My husband and I went for an appt today. The baby had the Dr, my husband & I laughing when she was trying to listen to his/her heartbeat with the Doppler. The baby was moving so much the Dr had to keep chasing after him/her with the Doppler. It was so funny. The Dr was finally able to get a quick read on the heartbeat but only for a few seconds (150-152 BPM) lol. My Dr said lots of movement is a good thing, she also couldn't believe how big I looked at 18 weeks, she said I look like I'm 22 weeks! I certainly do fell big lol. Do any of you have any funny stories to share?
