Mucus plug , early labor ?

So last night and this morning I'm continuing to lose my plug. Last night it was A LOT this morning was just a little. But since last night I've been achy all over my body and having cramps ( nothing too painful) just enough to know they're there. Anyone else experience this and go into labor not to soon after? 38 weeks! Ftm so I'm not too sure what to look for or how to feel lol , I was at the doctors two weeks ago and was 1cm dilated if that has anything to do with it
