Confusing braxton hicks

Ye

I’m 35 weeks 4 days and I’m confused if I should be alarmed or not. I get a lot of Braxton Hicks throughout the day but the last few hrs I’ve been gettin about 5-6 in one hr but the abdomen tightness only lasts like 10-13 seconds, in which they take my breath away. No pain just pelvic pressure when I get up. Should I be worried, is anyone else ever gotten them like this? I have a dr. Appt in 1 week.
