I am 40 weeks tomorrow and am seeing the midwife today. I am ok with going overdue but my pelvis/hips/inner thighs are starting feel like they might drop off! I get very stiff whenever I sit down and am struggling to get up, plus have been virtually housebound for about a week as walking for any distance makes my lower back completely seize up. How likely am I to be offered a sweep today? Or is that something they only do once you're overdue?
