Braxton hick contraction or something else?

m
I'm a FTM so not sure what to expect. I'm due in 7 days and the past couple of days I feel the baby move down around my belly button or just below. Then my stomach gets hard tightens and kinda hurts.  I thought it might be BH but I thought those don't hurt. I usually get a couple of these lasting just about a minute or under but then they go away. Any thoughts on if it's BH or a contraction or just symptom of baby moving ?
