I have been off the pill for about 2 years and I am going on vacation May 3rd - 9th. My period is scheduled to start on May 4th, how can I make sure that I am not on my period during this week.

I understand that if I start to take the pill again it maybe possible to ajust my schedule but I am not 100% positive when I would start the pack & for how long I would have to take the pills for. Do I have to take the entire pack (21 days)? I rather not as I tend to gain weight and again I'm going on vacation (bikini wear).

I sill have a pack of YAZ which doesn't expire until 2010 (wow, didn't know they lasted so long). So if you can please advise when I should take the pill and for how long in order to delay my period by one week I would be greatly appreciative!

Thank you!
