Help please! Maybe Labor?

I’ve had a ton of lightning the past few days and baby is far down in my pelvis (so much so that I have hemorrhoids from the pressure) I’ve lost little bits of what I believe to be my mucous plug but as of yesterday I started having a lot of contractions that weren’t consistent but pretty painful. By night time last night my acid reflux hit harder than I’ve her experienced in my life and I was up pretty much all night due to that and the cramps I was feeling all over my belly. early this morning nausea and vomiting set it and now I am having loose stools every 30 minutes. Does this sound like I could be going into labor. I am 36+6.
