Flutters at 15 weeks?

So normally if I feel any kind of bubbling it's usually high up and tends to be gas. But I'm at work on a night shift right now watching the newest episode of Riverdale and I felt quite literally a flutter, similar to the bubbling but much much lower down, right where baby is. Could it be the baby moving? I feel like 15 weeks is way too early, I'm plus size and this is my first baby.
