I am sorry to say this, but I had the same thing when I went into labour with my DD.
For a few weeks before I gave birth I was having niggles every day and back aches etc. But I asked my MW about it and it is completely normal. If you can breathe and talk through your pains and they are bearable and stop if you move around, then it's not labour.
If there's one piece of advice I was given before I had my DD that I remember regarding labour - is; you will know when they are labour pains!! They will usually be regular ie. coming every 5-10 mins and lasting 20-60 seconds. They usually start off slow, build to a peak and taper off.
There are a few signs you will notice before going into labour such as the plug or show, waters breaking and very painful contractions!!
Good luck with your upcoming birth babe, not long at all now smile
