Signs of pre term labour?

Lizzie • Mum to two girls.
Hi ladies, I'm 35+5 at the moment and yesterday had some spotting. I went in to get checked by the mw as I've been having light on-off period like cramps for a few days now. Bub was fine and happy and my bp and heart rate were all normal so we went home (I declined the internal!).
Today I had a glob of thick, snot like mucus after weeing. It was snot like enough that I could stretch it for about 10cm between my fingers. My question is, are these signs I'll be in labour soon? I still have my on off cramps, have my next mw appointment next Wednesday... Hoping bub stays in for at least two more weeks!
