36 weeks and Braxton hicks

Nicole
So today I'm technically still in the 35 weeks but i start my 36 th week tomorrow so... 😜
Anyway, anyone else experienced Braxton hicks. My first time was like week 22. Then nothing for a while. But after passing the 30 week mark, I would get them maybe once a week. And now it's been a little more frequent. Also, the further along I am, the more intense the BH become. 
The one I experienced at 22 weeks was nothing. There was a tightening of muscles but not painful. And that was because I went for a longer walk with my dogs than I should have. 
If you haven't felt them yet, mine start out as a tightening in my back, right at  my tailbone, then the tightening travels and grows around to my lower abdomen. Clamps down pretty hard. This all lasts maybe a minute but it feels longer. 
Just curious if anyone else has experienced these and I guess I'm kind of giving a heads up if you haven't yet. I hope some of you are lucky enough not to feel this at all.
