Labor 33 weeks 6 days

I've been having pain in my lower pelvis since Friday night, and my lower back pain has gotten worse. My mom and husband want me to call the dr because they think I'm going to go into labor soon, but the pain isn't debilitating it's still pretty mild. My sister is a L&D nurse and she told me that if I start getting menstrual like cramps to call my dr. My dr is saying if I have bad contractions to come in. But I don't know what they feel like! Everyone says different things, so now I'm worried.
