I had been taken into hospital on the 31st due to regular contractions that were 3 every 10 minutes, however they slowly died off and are still on and off since I left hospital. Now I'm having full stomach tightenings as well as pelvic pressure but little pain. My mucus plug has started to come away and my back hurts like mad.  Could this be slow labour? I was examined while there once and I was 1-2cm dilated could that have changed?
