pain where my pelvic bone is at 26 weeks...

Abby • 33 years old. Married to Eric. Mom to 2 boys that are 3 years old and one year old!
Okay I may sound crazy but I get sore where my pelvic bone is...is this normal at 26 weeks or should I be calling my OB? I do a lot around the house and work out at least three times a week I'm wondering if that could be it...🤔tia
