IUD Insertion and exercise/bloating

Kelly
Hey guys! So I got my first ever IUD fitted on Tuesday and we're two days on. I am a massive gym goer and I'm worried about exercise, can anyone advise?! 
I don't know if I'm Ok to go back to the gym? 
Also! My lower abdomen is so bloated and solid, any ideas how long this should take to subside? My doctor didn't really talk through it that much :(
