Spasm like fetal movement?!?!

26 weeks and have been feeling my baby girl roll and kick since 20 weeks. Her kicks are SO strong now but i’ve been noticing i’ve been feeling spasm type movements in my stomach, more on the sides kinda by my ribs but i know it’s not kicks because i know what those feel like. It almost feels like a muscle spasm but in my stomach. I had someone tell me it’s quickening but i read that quickening is the first fetal movement you feel and i’ve been feeling my daughter move for weeks now so i’m confused on what it could be. I only ever notice it when i’m laying down for bed at night and i don’t think it is hiccups either.
