Braxton hicks I need some info? And TMI

Ja
I'm a FtM and I just wanted to know what do Braxton hicks feel like?? Really bad cramps or??   is it kind of that feeling vvvvv
I had a MC last year and had really bad cramping , pressure ,tightening 
lasted 14 hours they got stronger with in 8 hours came n gone every 20 to 10 to 5 to 2 mins I even had to push my placeta out at home 
I know everyone feels different things I'm just guessing the mc pain is the same as Braxton hicks? Like I said I'm new to this 
And I am currently pregnant and just want to know how it feels
