Try getting in the bath, see if they continue in the next hour or 2, if they continue call your doctor to see what he wants.
I had more than 5 in an hour but dont hurt
N braxton hicks are not contractions and do not mean labor, very different things. If you thunk you've had BH more then 5 times in an hour that indicates it could be real contractions and yiu should call your doctor if your preterm. If your not preterm then take a bath and see if it changes.
