Switching To Another Pill!!!

I need quick help! I am currently in the placebo week of the pill I used here in Mexico. I had to switch because CVS wouldn't let me take extra prescription so I had to change my pill here.

ANYWAYS - I return to the US mon/Tuesday and my placebo week ends on Saturday so id have to start with the pack again on Saturday. However, I really want to start with my prescription from the US. But since I won't be back in time I'm thinking to take the pill I've been taking here until I get to the US so that I can right away switch to my original prescription.

Have any of you ladies switched to a different pill right away -- not waiting to finish the pack? I don't want to wait until I finish this pack id like to go back to my old pill as soon as I get home.

Thanks!
