What would you do? Help please

I have this sharp/pinching feeling on the right side of my belly.. It's right at my pant line and close to my hip. My mom thinks it might just be growing pains.. But I also have a problem with a varicose vein that keeps sweeling on the right side as well (my dr is aware of that) should I call the dr about the pain? Do you think it's growing pains? I'm 28 weeks and 1 day. Thank you for any advice!
