Braxton hicks at 23 weeks 3 days?

Amber

So for the past 2 days I feel like maybe Ive already started having braxton hicks. Starts just above belly button then I feel down low, not painful at all. I also have been feeling a big stinging feeling everytime he kicks me in my bladder and have been going pee constantly but unable to just release it all it feels like. No burning when I urinate and no fever. I dont recall experiencing this with my first three. Baby boy is still super active. Not quite sure. Have appt tomorrow and live 70 miles from my OB. Any thoughts?
