Im pg with DC2 and had none of this with DD 
Every night for at least the past ten, I have been plagued with stomach tightenings, cramping pains in my uterus and tingly aches running up.and down my thighs. Add in lower back aches and Im spending half the night thinking "is this it?!"
Am 38 weeks tomorrow so it will happen sometime soon, but Im frustrated by all this coming and going.
I have no babysitter for dd this weekend (Mum is away but will be back Sunday evening), so am fretting about that too, even though if I do go into labour we will just have to manage, but its an added concern when it would just be quite nice if mt body could just relax until the Big day.
I get daily tightenings too - stomach rock hard like a basketball for most of every evening. I am wondering if it will all.make for a smoother, swifter birth, but I really think that is wishful thinking!
