Prodromal labor??

So last night I was having what I think were contractions (40-50sec long every 5-10minutes) it wasn’t painful just felt very uncomfortable and kind of like a burning sensation. My stomach would harden and baby kept pushing down with each one. It went on consistently for almost 5 hours no matter what I did (lay down, walk, sit) I showered and then shortly after 11 they stopped. It really felt like the start of labor… I’m curious if this could’ve been prodromal labor or if it was the start of labor and just fizzled out… this is baby #3 too and with my last 2 my water broke before contractions even started. Has anyone else had a similar experience?
