Steady contractions now nothing

I'm 35wks today, yesterday I went to l&d for contractions. They weren't painful but I could definitely tell they weren't Braxton hicks or anything like that. They were regular for a couple hours then they just stopped. Has this happened to anyone else? I really thought he was going to be here within the next few days but now I feel "normal" again so I'm curious as to what might happen!
