Hi,
I'm 38+2 with my first pregnancy. Lost my plug yesterday and had lower back pains on and off. Woke up at 5 today and have had period pains and really crampy diarrhoea since. Back is still aching and everything just feels generally achy. Also, having LOADS of discharge.
The thing is, I can't really say I've noticed tightening other than the period cramp feeling, and nothing seems regular or frequent enough to time.
Could this be early stages of labour, or is it just things moving around and shifting?
Things feel very different today, but I also don't want to spend the day on tenterhooks analysing every twinge. As this is my first time, I would really appreciate thoughts from anyone with more experience 
Thank you
