At the moment Im 39 weeks and have had stop start labour for 2 weeks with full contractions a show but nothing regular. I am about 2 cm dilated but have been for a while. I have had BH since 25 weeks.

With DS I got to 40 weeks had a big show and was about 2 cm dilated from 38 weeks. BH from about 34 weeks.

Pre labour is different for all, I say just go with how you feel. It's normal to turn inwards and not want to be around others much, it's your bodies way of helping you rest and prepare.
