Early labor? FTM?

I’m 40 weeks 1 day and had a check yesterday only 1 cm dilated. I don’t usually bleed after being checked. Today I have had on and off period cramps that are super painful and tightening. I’m losing small pieces of mucus plug still but today it had strikes of brown ish blood... ftm and trying not to get ahead of myself but just not sure if this is early stages of labor or just normal for being full term. Any words would help! Thank you xo
