Should I stay or should I go now?

According to my office I am 34+3 but I know when I conceived and my last period so I am 36+2. I am measuring 39 weeks and baby was already 6 pounds at exactly "33" weeks, engaged and I was 1cm dilated this past week. Tonight I am contracting every 4 minutes and I have bad diahrea and this horrible achy torn muscle pressure all over my lady area.

Could this be it?! I REALLY don't want to go just for them to tell me it's not, stop labor or send me home. I've been to labor and delivery FOUR times since I was 29 weeks and they give me procardia and keep me all night and then just send me home. I'm just over it and no one listening to me. 😭
