Third baby, 40+5, trying for a home vbac
Previous stillbirth and sections so this is my first 'normal' gestation and labour.
I had a sweep on Sunday and been losing bits of mucus plug ever since, no bloody show though.
I've been getting irregular contractions since midnight, sometimes 1 every 10 mins, sometimes 1 a minute. They take my breath away and I feel like I need to poo with each one. Also have a fair bit of back pain but this is pretty normal for me.
I am constipated and have terrible wind 
Could this be labour? Should I take any paracetemol or Fybogel or anything? If I'm going to have a baby tm I'd really like to get some sleep and at the moment contractions are preventing that.
