So confused

I started having contractions at 6 on Friday and it's since been 12 hours and I'm still getting them. It's started to gain a bit of a pattern with the contractions being between thirty seconds to a minute long with breaks of three to six minutes in between. I just don't know if I should head to the hospital or not yet because my husband works a hard job and is really tired. I really don't want to wake him up just to be sent back home.
