Does it feel like trapped wind? I am 5 days overdue so am expecting things to kick off soon. I am getting trapped-wind pains which don't last very long. On and off. Earlier today and yesterday I had pre-menstrual symptoms, a bit crampy and uneasy in my tummy and a bit of backache. Now I'm sitting here having these little "contractions". Do the real ones last quite a long time? I wonder if it's just a blocked-up system. I haven't been to the loo properly for a couple of days. Apologies for that
