Having Contractions

I am 2 weeks out from my due date, and I'm starting to have contractions. Tonight, it feels like one big contraction that won't stop. I can't say how far apart they are, cause I can't quite tell. They are not really painful though, so I'm not too concerned. I have a doctor's appointment with ultrasound tomorrow, so we'll see how much progress has been made... Fingers crossed that she'll be here soon!
