Early signs of labour?

I’m 32w2d. First pregnancy so I don’t know much. I’ve been having vaginal pain/discomfort for a couple weeks now, today I had a loose bowel. And for the past few days I’ve been having a cramping feeling in my lower abdomen with lower back pain as well and tightening of my belly. All these things happen when I’m laying down, standing, walking and relaxing. I don’t know anything about labour or what to look out for… if anyone can let me know if this is normal? Thanks😊
