I'm going on vacation in August, it's all booked and then I realized something. My wonderful period will be arriving at the beginning of my vacation Lovely. I am on HBC (Alesse) and I'm looking for opinions about stacking. I was thinking perhaps this month I will take an extra week of pills in hopes to move my period by a week so when August hits, it will be on a totally different week. Or, am I better off just continuing taking my pills as normal and then in August just take an extra week of pills?
