If the rights-holder is releasing the explicit version on the 19th you will have to wait until then if that's the version you still want.
If instead you now want the clean version cancel the pre-order for the explicit version (Pre-order apps, movies, music, and books from the App Store, iTunes Store, and iBooks Store - Apple Support ; if it hasn't been released you haven't been charged yet) and buy the clear version instead.

I pre-ordered an album and it came out today, but iTunes says the release date is not yet.
