Good evening, mamas and expecting moms! 39 weeks, my belly is pulling, but I'm not timing it, that happens sometimes, but today all day, it's been getting hard, water and plug haven't moved, and on top of that, my bones are aching where my bum is? like for several days now, second birth, maybe someone has had this?
