When to worry over Braxton Hicks? Any personal stories welcomed

Ka

I’ve been having Braxton Hicks since about 20 weeks pregnant. They aren’t painful just comfortable. But they do come often mostly in the evening sometimes I know it’s because of being on my feet all. I do have to mention I hydrate a lot. Just wondering when I should worry? This is my second and with my first Braxton Hicks did not start until well into my my second trimester I would say about 33 weeks.
