Did I have Braxton hicks or a few real contractions?

I'm only almost 33 weeks but I am high risk bc I have poly. I have had 2 previous boys and I had to be induced so I never really had an early labor signs anyway how they felt it was just 3 of them about 5 mins apart lasted about 45 sec to a min strong lower back pain that went up to my tight stomach it was I would say a 7 out of 10 it was enough pain for me to put my food down and hold my back and started breathing hard after those 3 times I have been fine nothing else has happened so is this like my body having real ones getting ready for something or just BH??
