Can I use the free month code before my sub kicks in?

Hi,


Ok, I took someone's referral, so I have 7 days of Premium time, but I started my subscription, and it says I'll be billed on the 4th of March. Since I don't wanna mess anything up, since I'm technically Premium at the moment, can I put in the Sharethelove code, and it'll work, or do I need to call Customer Service?



Please help.

I didn't find the right solution from the Internet.
