Signs of labour?

What happened before you ladies went into labour? I’m 35+1 and I’ve been having strong braxton hicks for a few weeks, I now have a sudden burst of energy and urge to nest after being so tired all this pregnancy and loose stools + on and off back pain could this be that labour is near? I had a positive fetal fibronetcin 6 days ago but I’d had sex within 24 hours of the test so it’s not really reliable
