Baby movement?

So I’m a FTM and I’m 17 weeks and one day. I’m laying down on my back currently, and started to feel movements in the lower right side of my stomach. I placed my hand on my stomach with a bit of pressure, and felt a pop (I can’t explain, but it felt like something tapped where I placed my hand). I was feeling these movements for a little bit before I placed my hand down. Is this possibly the baby moving around, or could that be a gas bubble popping? It felt quite strong where I placed my hand and I don’t feel these movements need to fart at all, but still unsure. I’m just so excited to feel the first kick, and I’m hoping that was it.
