Tan Sunless Tinted

How can i figure out if my sunless tanner is waterproof?
I am currently using Loreal Sublime Bronze Dermo Expertise, a gradual tinted gel sunless tanner. I am going to a pool party in 5 days and wanted to know if i would come out of the pool blotchy or wash away in the chlorine pool.
Most of thos self tanners last about a 2 weeks max and wont come of unless you scrub at it
