Feeling one baby more than the other


Is it normal for one baby to be more active? I feel my little boy pretty often but I only feel little girl maybe once for every 10-15 times that I feel boy. At my last ultrasound, she was super chilled out until she rolled over and started kicking up a storm and then she rolled back to sleep but it still makes me nervous when I feel boy but not girl. Also I’m 19+2, pic related lol
