Anyone have trouble finding baby's heartbeat now that they're further along? I don't use it much anymore because I normally feel him moving but today he was being quiet so I used it and it took me forever to locate it but it sounded like he kept moving. Once I found it it sounded a little different but it registered 144 so I know it was good. I had hardly any gel left so I think that was part of the problem as well. I need to stop freaking out! 😣
