Advice please)))

Ftm overhere. Ladies, tell me how false contractions feel like. Im 37 weeks. Almost there) time to time i get this tightening in my belly that lasts like 3-4 seconds, the belly gets really hard, takes my breath away and the that thing stops..... I had them yesterday like 10 times throught the whole day.  What is it? Can i reffer it to a false contraction?
