Too early for Braxton Hicks???

I am 22w, almost 23w. This is my second pregnancy and everything has been healthy. The past few days, I’ve been getting Braxton Hicks contractions throughout the day. I’m hydrated so I know that’s not the issue. I don’t remember them happening this early in my first pregnancy. Has anyone else had this early on? Would it just be because of how active the fetus is or how active I’ve been with work and my daughter? I’m not having any other complications so I don’t want to call the doctor.
