Do you still feel the tightening or is it painful compared the BH?
I'm the same way. This is my first pregnancy and I'm currently 38w 2d and I've only experienced a real contraction a handful of times. I have had braxton hicks many times. You'll be able to tell them apart because with regular contractions they feel like period cramps and you may experience lower back pain with them, I do. I was like 34 weeks when I first experienced them.
