A sound was played on my Apple Watch out of the blue. 13 times.

Out of the blue, my Apple Watch started playing a sound and I received 13 emails with the title “A sound was played on *your* Apple Watch.” No one had access to my other devices and I was watching TV when that happened, so not on any of my devices. The sound on my Apple Watch was the same sound an Apple device makes when you ping it on ‘Find My’ from another Apple device. Each time I ‘Dismissed’ it, but it would come back. It did so 13 times, until I changed my Apple password. Is it a stretch to think my account had been compromised?
