Baby Switched Sides?? (14 weeks)

Ashley
Had a brief scare today when it took forever to find our little bean's heart beat on the home Doppler today. Normally, we can find it within 30 seconds, but it took close to an hour on and off before we finally found it. Just came home from work to check, and couldn't find it. Finally, my partner suggested we check the left side, and BAM!, there goes the heartbeat. First time we've ever heard it on the left side. Anyone else ever experience this ( have the heartbeat show up on the complete opposite side)? Is it common for the baby to move over that much at this point? This is our first, so we are pretty clueless. We are 14 weeks as of today.
