Sent me home. In so much pain

My due date is in 2 days and I started having contractions every 5 minutes so went to hospital. I was 3cm dilated when they checked me and kept me for 2 hrs to see if anything changed. They ended up sending me home and said to wait until my contractions are 2-3mins apart. Since I’ve been home I am in SO much pain (8 out of 10). But my contractions are ranging from 5-7min apart. I can’t imagine waiting until 2-3mins apart. Should I go back in based off of my pain level? I could cry based off of my pain level
