preterm?

Summer

I feel like when I try to move around a lot it hurts. and that's not normal for me. I carry grocery's home, walk my dogs, clean the house etc. up and moving. but its gotten to be painful? baby is still moving around. feels like he moves a lot at night. feels like it goes from my upper hip bones to pubic bone area. I've never had a pregnancy last until 30 weeks, is this just round ligament pain? is it just growing pains?
