What is going on?!

I'm 39+5 today, and miserable. I lost my plug 2 weeks ago, have had 2 stretches, I'm at 3cms with a "soft short cervix" since Wednesday, countless false alarms, I have had loose BM'S and the last two days I've had a discharge that's almost slightly green? My underwear is damp but no crazy rushes of fluids. Baby moves lots. The false alarms consists of almost an hour of constant cramps that come from the back to the front, take my breathe away, don't stop when I walk, but then just poof go away. What is going on?!?!! 😢😨 I'm a second time mom I thought they come earlier 😭
