Cannot feel Baby movement - 21 weeks

Hi! I am now in my 21 weeks. I’m having a baby girl but until now l, I still couldn’t feel her kicks in the tummy yet, doctor told me she still small, might need to wait till more weeks. Nurse told me cos of my thick fibroids outside uterus. My sis experienced movement when she was alrdy 21 weeks but having baby boy at that time. #firsttimemom Anyone had some experience as me?is it baby girl abit slower 😅
