I’m currently 29 weeks pregnant. Should I worry about this?

I am currently 29 weeks pregnant today..

Today I’m experiencing cramping which I know it’s “normal” but the first time it happened it lasted an hour long on Saturday 27th. Then happened the next day the 28th for maybe thirty mins.. afterwards that week on and off for less than 10 mins. Today now is the 5th and it’s almost been an hour again. Should I go into the hospital?
