I'm 40 weeks today, and for about 6 hrs my back has been killing me. I haven't had any back pain this entire pregnancy. This is my third baby, however, I was induced with my first 2 so I don't know if I'm in actual labor right now. The pain is CONSTANT, and in my lower back. Sometimes it gets intense, but other than that I really just feel in constant pain. Have any of you experienced this, and it be actual labor? I hate to go in, and it ends up being NOTHING. My husband works out of town, and I have 2 kids that have school in the morning, so I'm trying to avoid wasting everyone's time. Thanks for looking!
