Pulsating in right breast help!!

This is going to sound weird but has anyone ever experienced a pulsating/slight shocking feeling in their nipple/breast? Mine is just my right side. It almost feels like the tree of life pictures look when people are breastfeeding lol it’s that same pattern. I don’t believe I’m pregnant (test haven’t picked up on it at least - should be in my tww) not have I ever had any children. Just wondering if this has ever happened to anyone else? It’s been going on at random times for three days for me.
