Baby Moving?

Okay guys.. I'm a little confused & not sure about something.

I'm 17 weeks 3 days. I was laying on my right side when I went to roll over to my left side. When I went to roll over, I felt a pop in my upper belly on my right side, it felt like a bubble pop. I went to roll back over to my right side and I felt it again.

Could it be baby moving that I'm feeling?! I haven't noticed flutters or anything and I'm so curious as to if it was the baby that I felt!
