Baby kicking or contractions/braxon hicks?

I'm 22 wks and for the past 3 days I feel a wave of what feels like consecutive kicks but they're not super strong or anything but enough to alarm me and stop what I'm doing. They're back to back with no pause between them and I feel my stomach sort of pulse for like 3-5 times. It it baby kicking or flipping or something else like contractions/braxon hicks? I feel it throughout the day but it's not just once but like kick kick kick kick or pulse pulse pulse.
