Never has this with the other 2, but I'm 37+4 and baby's head has been engaged for a week or so. I'm sooooo uncomfortable. The pressure means I now have varicose veins 'you know where' (sorry, TMI?) and can't comfortably stand for long. but in the last couple of days I've been more concerned because I can't sit down without the tops of my legs getting sore and going numb. Any advice?
