Girls, hi. 34 weeks pregnant. Today all day I feel discomfort in my belly. The baby is moving very low, like it's going to pop out now. My lower back hurts. My belly also feels squeezed, like it's about to burst. Lying down is uncomfortable, sitting too, standing is impossible altogether. Has anyone had this? Is this normal?
