You can keep measuring even while traveling and/or on holiday, and we'll go through the guidelines below.
If you travel across several time zones and experience jet lag then we recommend you mark your temperatures as "excluding" until after the first night of sleep after arrival. After you have adjusted to the new time schedule, you should measure as usual when you wake up in the morning. Remember to always mark your temperature as "excluding" if you feel hungover or if you have slept less than usual, or had a sleep-in.
It’s also good to know that traveling can be stressful on the body, which means that it can sometimes affect your cycle and cause a delayed ovulation for instance, and therefore a bit more irregular cycles.
