how long do labor contractiins normally last?

I had them all day, then my baby was born that evening. But I was full term, dilated, and completely thinned out.

yeah but where they lasting a min or less

Like each one? Or how long do they last in total during labor?

I can't remember exactly but I think its around a minute? They usually tell you to go in when they are a few minutes apart.

well ive been having them every 5 min and last about a min

You shouldn't be having them at all. Contact your doctor or go to the ER
