Labour????

Woke up this morning and felt so motivated to get my shit together which doesn't usually happen because it's so painful to get out of the bed. Woke up 8ish. Had a shower 9ish felt a really strong braxton hic around 10. Since then my back feels all wrong like its tense. I have pressure in my ass and when they come they make me breathless . Really aching in my lower half. Is this early labour. This is my second child I'm 38 weeks. With my daughter I went from no contractions to pushing her out I never had a build up not like this. I haven't had my mucus plug come out but tonnes of green discharge. I stand up and the pressure is worse down there
