Contractions that won't stop

Sj`s Mommy
I've been contracting since 5pm ladt night. It's now 4am and they haven't let up at all. I'm getting about six an hour but they aren't very strong. They're a little stronger than they were at 5 but not much. Hubby and I even went to walmart and I had three just walking around. I've drank water, walked around, sat and laid down and they're still coming. I can talk through every one of them with no problem and only like 3 have been a slight bit painful. Anyone else having this?
