We have designed inne to become part of your daily routine, and taken all possible risks into account to keep you safe. At the same time, travelling or any significant disruption to your routine may lead to changes in your menstrual cycle. Therefore, it’s essential to know and expect potential shifts or changes to your period and ovulation dates as your body adjusts in those situations.
However, it does not mean that you should not use inne if you expect to travel, work night shifts, or suffer drastic alterations to your lifestyle. By contrast, measuring consistently in these situations can help you better understand the changes you are experiencing. For example, even if your ovulation shifts due to a change in your routine, inne will be able to detect and confirm once your ovulation has taken place.
Progesterone, the hormone detected by the Minilab, has a cyclical behaviour. During the first phase of your cycle, the follicular phase, progesterone levels are, by definition, very low. Therefore, any fluctuations during the follicular phase are also rather small, and will not affect your inne Minilab's ability to detect your ovulation.
Following ovulation, the released egg leaves the corpus luteum behind. The primary role of the corpus luteum is to help prepare the uterus for the implantation of a fertilised egg, and one of the ways it does so, is by secreting high amounts of progesterone to stimulate the thickening of the uterus lining.
This very rise in progesterone levels during your luteal phase is what your inne Minilab relies on to confirm that your ovulation has taken place. In other words, your progesterone levels are primarily determined by the activity of the corpus luteum, rather than by your circadian rhythm. If you are travelling and find yourself in a different time zone that affects your usual testing window, please don't worry - just continue your daily inne ritual in line with the local time.
