Hi all!

I'm almost 36 weeks preggers with my first bub. The last few days I've been having quite a lot of painless tightening of my uterus, a bit (but not much) of pain in my lower right side and some diahorrea. Today I have also felt some stinging in my vagina, though not when I pee. Both my brother and I were early, as well as my mum and all of my aunties and uncles. Could this be a sign of pre-labour or am I just being optimistic??
