Contractions question!

Hailey • Kinley Sophia was born in July 2015 and Theos Aiden born January 2017
Yesterday I did a stress test and found out I was having contractions every 5 to 7 mins but all I was feel was a little bit of pressure nothing painful. I have that same feeling and I'm having them almost every 5 mins. I feel weird going to the hospital when I have no pain. Is this normal? What do I do?
