Is it okay to go to a water park?

This saturday i'm going to this waterpark, it has a wave pool & some slides. I was wondering would it be safe for me to go on them if im pregnant? I'm not sure if i'm pregnant yet, i'm on day 36 of my 35-39 day cycle so i'll find out in a couple days if i don't get my period. But do you think it would be okay for me to go on the waterslides in a raft?
