Sounds like early labor to me! I'm due in 5 days having the same. Mine were about 10-15 minutes apart yesterday and are 7-8 this morning.
Iv got three days left and having the same kind of period pain but nothing else :( have u lost your plug yet? And unfortunately there's just no way of knowing just trust ur body will go when it's ready I'm so fed up of waiting but have come to the conclusion baby will come when ready lol, they sound like practice contractions if they get worse and closer in time then it will be real labour x
