Is anyone else experiencing horrible lower back pain??? I'm cramping in front some but I think that's because of constipation but my lower back is KILLING ME. I'm 10 weeks 2 days. I've had it for weeks now but it's getting worse. I don't remember having lower back pain last time. & I don't have a UTI. on top of the lower back pain, my left buttcheek/hip/thigh hurts from my sciatic nerve pain & didn't help when I ran into baby gate...but I'm mainly worried about the back pain.
