Silly question- baby movements

This is going to probably sound so silly, but I want to know. 😂

I got a fetal Doppler to use at home, and like everyone else, I find the heartbeat right above my hairline under my belly button. The past couple days, I’ve noticed a few flutters, and even this one particular moment that felt like someone took their finger and briefly moved it along the inside of my stomach, pushing out. But all of these feelings, I have felt on my right side. Could that be the baby?? Or maybe I’m just TRYING to feel movements! 😂 I’m 13 weeks, 2 days, so I know it can be early to feel anything as a FTM. 😊
