diarrhoea 38 weeks.

I'm 38 weeks tomorrow and for the past three days I've had very very lose stalls. Thursday I went for a poo 5 times throughout the day, yesterday I went 7 times and today I've gone 6 times so far. Normally I only go once a day, twice if I'm lucky. I've been getting more cramps in my stomach on and off, I'm also getting cramps in my upper legs. I believe I lost my mucus plug two weeks ago (I had a small bleed two weeks ago also) baby is still moving around a lot but has been quiet more than what he usually is. I'm struggling to walk now so I'm guessing I've dropped, I pretty much waddle around and it hurts my hip and back to walk. I'm praying this could be the pathway to me going into labour. Anybody else experienced this? :)
