17 weeks baby movement?

Mary
I'm a plus size lady, so I haven't been able to see any movement, but I swear all week I've been feeling baby move. A friend told me I should be feeling it just a few inches above my pubic bone, but I'm feeling it much higher, sometimes even above my belly button. Is this possible? I know everyone is different, and I do have a short torso, so I'm still thinking it's baby!
