Going to a festival

Is it safe to go to a festival 20w pregnant? I haven’t brought tickets but was considering it, wondered if anyone had done anything similar? It’s a pretty big outdoor festival so i can choose to be away from the crowds but still enjoy the music.

I would never do anything dangerous so want to know if people think it’s a good idea or not. I’m a FTM so everything is still new to me, not sure what i can and can’t do!
