I'm sitting up in bed, and I've been getting "lightening pains" and TMI but as I'm sitting here I've just got the worst pain that felt like it was in my urethra, a sharp sudden shooting pain worse than I've ever felt. It lasted a second or two then stopped then came back again. I'm hoping it's over with now but I'm wondering if this is normal or something I should worry about? I'm 38 weeks tomorrow.
