Is this her moving or kicking?

Kassie • After 9 years of TTC, 6 MCs & never giving up hope, LENNON HOPE finally arrived as did her surprise sister, LENA LAYNE 22months later.
I'd love everyone's input but I'm really aiming this question to my fellow plus size mommas.
I'm 16w2d and today I began to feel what I can only describe as small pinches or cramps on the inside of my lower abdomen; they're very small, nothing like the cramps I used to have early on in my pregnancy. These are like little pin point pain spots that last for a second or two, move from spot to spot and are gone.
Do you think this her moving or kicking me or something else..?
