Baby movement

Christin • FTM with little girl Rosalie Arabella💕
This might be a stupid question but I'm a FTM. Here probably the past 2 weeks my baby has been "kicking". It feels like a thump not flutters. My husband has even felt them and he says it's definitely kicks. I'm 21 wks and 3 days. Is this normal for her to be this strong already? Has anyone else had this at this many weeks?
