Is it strange that I don't remember what contractions feel like?

It's been almost 7 years since I had my first son. When the doctor asks me if I've been feeling some contractions, I can't give a straight answer. I've been feeling pretty bad for the past hour. Tummy pains, some tightening, pressure in my back/butt. I don't need to use the restroom or anything. Surely those are Braxton hicks? 😕
