Skipping period on Nuvaring: 4 weeks in, 1 week out?

[ezraslaststand.livejournal.com]

Hi. I read the memories pertaining to skipping your period with the Nuvaring, but they didn't exactly answer my question. Others have posted about keeping the Nuvaring in for four weeks, taking it out, and then immediately putting a new one in for three (or four) weeks. My period is due to start on the first day of vacation with my boyfriend (how convenient!), and I'm wondering if it would be safe to leave my Nuvaring in for that extra week, take it out after four weeks and have a period, and then put another ring in for three weeks and continue with my regular cycle. Has anyone done this? Did it mess up your cycle?
Any help would be appreciated. Thank you!
