Contractions

I have been having braxton hicks for a while but i have now been feeling really intense pains every so often. I am going to track them but could i mistake it for poo 😫😫ive just been on the toilet and tmi but did a little one but the pain has gotten more intense after sitting and nothing coming out. Ive come back to bed and the pains still there. Its lower down tho doesnt feel how i was told contrction would feel (like a wave startinv from the top). Anyone else had this and actually been in labor?
