Early labour sign or nothing?

Na

I’m 40+1 today and this morning when I went to the bathroom there was a (non-mucusy) pink streak on the toilet paper. I’ve since felt ‘damp’ but not like anything is trickling or leaking reallt. I’m feeling pressure in my lower stomach but have had no pink streak when I wipe since. Could any of this be a sign of labour being imminent, or just normal late pregnancy?
