Labour!?!

Dee
I'm hoping this isn't false labour again. 
I've been up for past 3 hours and they are lasting a minute to a minute and a half. Coming every 6.30minutes to 10 minutes. I've never been in natural labour due to being induce as was high risk last time. 
The cramps really are low in my tummy and pressure in my bottom, bowels are empty as can get. Stomach goes rock hard too! Help!?!
