I'd say things were starting up! 
But, just so you know, I was in slow labour (after a sweep) for a few days with my first baby.
Had the sweep on weds pm and she was born 7am on sat.
It was really fri at around 11pm that things got urgent!
The Mdwf told me that she knew I wasn't in labour because I could still converse.
If you start getting regular pains, time them.
If they get to around mins between each pain, go in.
But, if you are scared and would like to be checked, I'm sure the hospital wouldn't mind.
It's really not so bad when you look back.
You really do forget it all anyway when you hold your little one in your arms and she grips your finger :)
Hey, it can't be THAT scary, I'm due number 4 in 18 weeks! :)
So, be strong and keep your eyes on the prize!
You'll be absolutely fine.
All the very best of luck xxx
