33 weeks contractions! Help

I'm 33w2d. At about 4pm at work I was having some contractions that were coming around every 5 minutes but they weren't painful and felt mild. I got home at about 5;30 and felt like I needed to go to the bath room and has some soft stool. Then I went and sat down and put my feet up and had a snack. I started tracking my contractions and they've been coming consistently now for hours but haven't increased in severity. I drank a lot of water and still have t stopped. I changed position to laying down and they continue to come but now feel different. More like cramping. Any thoughts or suggestions would help.
