Pelvic pain

I’m 24 weeks with my 3rd baby & I started having pelvic pain & discomfort about a week ago is this normal ? I know it’s a silly question but With my two other kids I’ve never had it this early so it’s just throwing me off a bit I should add that I do work & im more active with this pregnancy than I was with my other two I never worked while pregnant until now with this pregnancy I also have a hip problem & my back hurts all the time
