When you can time the contractions regularly, you're in labor. Regular being the key word. That's when u go to the hospital. But if for any reason, the pain becomes unbearable and your water has broken, go anyway. Chances are, labor will start n contractions will begin to come regularly
Sounds like your body is having practice contractions. I've been having mild contractions for five days and am 39+2 but it never builds into labor. When is your next appt? You can always mention it to your OB or MW when you get checked.
