Braxton Hicks..?

Jessica
How am I going to know if I have Braxton Hicks?? I know this seems silly but I have a very high pain tolerance and am know for brushing things off. I know ill be able to tell when Im really in labor, but I heard braxton Hicks arent painful..does everyone get them? Im 30w and feel like I should start feeling them soon. Whats your experience with this ladies??
