Gauging ears from 8 to 6?

so ive been gauging my ears for a little while... and it hasnt really hurt to bad. i went from a 12 to 10 in week and from a 10 to 8 the next week. both times my ears only hurt the first day or two. should i move up to six even though its only been a week. i know your supposed to wait a month between each gauging but if i plan on stopping at size six do i really need to wait? also can someone explain what it means to blow out your ear?
