You can manipulate your period if you are on hormones. You can force it to come early or postpone it safely for a couple of months. Many brides, with the aid of their doctors, post pone a period so it does not come during pre-wedding parties, the wedding and then the honeymoon. You need to be on birth control hormones for several months to be able to accomplish that safely without any break through bleeding.
I think if you are on birth control pills you can skip the placebo pills in your old pack and start right into your second new pack and this will skip your period.
