That's how the real thing often starts hun. You could try phoning your maternity unit for advice, but they'll probably ask you to go in, then send you home again - which's not very nice if you have some distance to travel to the hospital. Time your pains, and if they start coming at regular intervals, even if they're not very bad, then maybe you ARE in the first stages of labour. That's how mine were, and after 25 long hours, just when I was wondering when the pain was going to get really bad - my son decided to enter the world. It was quite a shock, as I'd expected much worse! Good luck.
