What do contractions feel like?

I had my 36 week check up yesterday and I got told I’m already 3cm dilated and I’ll probably go into labor before I hit 39 weeks. Today however I have been having these cramps that hurt to move or breath they last for probably around 1-2 minutes and then go away for 20 minutes or so. Are these Braxton Hicks or the real thing or something else?
