Braxton Hicks every 30-40 Minutes??

would you be concerned if you were having period like cramping all night and dull back aches along with some slightly painful/uncomfortable Braxton Hicks every 30-40 minutes even though they last about 10-15 seconds? they’re leaving me sore but aren’t taking my breath away. I’m hydrated and I’ve been switching positions and can’t seem to relieve them, 28weeks1day today.
