Sciatic nerve pain at 37 weeks

Yesterday I turned 37 weeks pregnant and I also started limping from horrible lower back pain. I call my OB today and he has me come in. He checks my cervix and is completely shut 😭 with my last I was 1cm by 36 weeks. Anyways he then tells me that the pain is NOT going away til I give birth. I wanted to cry. It’s only been 24 hours with this pain and I can’t take it. I just want to give birth already 😭😭😭😭 I have a feeling I’m gonna go over my due date with this one
