Did I hurt my baby???

I know this is gonna sound dumb and I’m gonna get “babys well protected in there” but need to ease my anxiety. I was laying flat on my back and moved my leg up and to the side quickly where it hit where I assume baby was. (Felt hard) it was on my left side.

I felt either a pop or babies sudden movement I’m not sure it’s hard to explain.

But it was enough to make me go “Ooooh!” Didn’t necessarily hurt.

Checked with doppler heartbeat seems fine?

I’m 16 weeks 2 days
