BH or real contractions?

I woke up this morning pretty uncomfortable, usually I'm super motivated & always trying to find little things to clean/organize but today... today I've been glued to the couch because I keep having braxton hicks & some back cramping. they're irregular, some are uncomfortable, some hardly noticeable. some around 2 minutes, some just a few seconds. I took a warm shower & even shaved, listened to music & just relaxed. any bit of discomfort i had went away, so I ate some leftovers & watched an episode of fixer upper (still obsessed lol) & I'm uncomfortable again... I'm 25 weeks. no spotting, no leaking, no loss of mucus plug, just belly tightening & back cramping... should I be worried? also drinking plenty of water. just had a check up yesterday- no uti or infections of any kind, also was fine yesterday. just a little confused. baby is moving a lot too if that helps.
