Braxton Hicks contractions every 5-10 minutes?

I just started to time and track them so I don’t have an exact pattern yet or anything but I’m definitely having some kind of contractions that last about 30 seconds every 5-10 minutes. They are not painful at all they aren’t really that uncomfortable to me either. I can feel when my stomach is starting to get tight then my uterus gets hard as a rock. I got up and walked through my house and drank a cup of water then laid back down and they are still happening. I’m going to be 35 weeks on Monday and I have a doctor’s appointment tomorrow morning. Is this normal? I’ll obviously discuss it with my doctor tomorrow but until then I’d love to hear from y’all lol!
