labor or not?

Haley
I'm having contractions every 3-4 minutes and my back is killing me. I've been having them for a solid 3 hours. No leaking water and no mucus plug that I've seen. I can't tell if this is just false labor again or if I'm actually in labor this time. They are getting closer together and stronger/more painful but so did my false labor contractions, so I'm confused.
