Baby moving??

So I’m 17 weeks 2 days. & I think I feel the baby move but I’m not sure lol this is my first so I’m not sure what to expect. It happens randomly & it feels like flutters almost idk how to explain it. But it’s enough to make me like woah what was that. It happens I noticed mostly when I’m relaxed laying down for bed, is it even possible to feel her move yet or is it just bubbles or air ? Like right now I feel it happening more like just in 4 min I felt it like 6 times 😅
