Postponing my period?

Paula • 22
Hey girls! So, I'm getting my period next week but that's exactly the week I'm going to be with my boyfriend traveling to a beach, so... well, you know. I'd like to postpone my period to like a week AFTER so I was thinking just keep taking the pills instead of stopping for the 7 days in which I'm supposed to get the period. 
Would that work? Would I get the period exactly one week after? Is it risky? 
I'm kind of afraid of doing that
Thank you!!
