Please help... lol

Okay this is gonna sound really weird but it’s the only way I know how to describe it 😂😂😂 I’m 14 weeks pregnant with baby #1. I’ve been using a doppler 1 or 2 times a week since i was 11 weeks to listen to my baby since I’m not far along to hear movements yet. Normal I hear a normal heartbeat that sounds like mine, only a lot faster and that’s how i know it’s the baby’s. However, today i listener and it literally sounded like the intro to Barracuda by Heart... 😂😂😂 I literally can’t think of any other way to describe it lmao. Is that normal you think?
