Contractions and labor

Megan

Alright ladies. I have no idea what contractions feel like. I have a little over three weeks left till my due date. My boyfriend decided to go down a really bumpy road and hit all the puddles tonight. For the past 30-45 minutes my stomachs been getting really hard and hard to breathe and making me have to lean back to catch my breath. Are these contractions and should i be thinking of going in to get checked?
