Advice PLEASE

I’ve been having constant back pain since 9/10. Definitely feels worse than earlier. I’ve tried walking, rubbing, switching positions nothing seems to help ease the pain. The back pain come and go pretty close together, but I don’t always have pain/tightening in the front every time. I’m 38 weeks. I don’t want to call my dr or go in unless I need to 🙄 I’m one of those people. This pain is just so uncomfortable I could about cry “not high pain tolerance”. I just don’t know if it’s back pain or back labor
