I often get up at night to go to the toilet or tend to my toddler. Will this affect my temperatures?
This will depend on your individual metabolism and how often you are awake. Record any unsettled sleep patterns on your chart. For many women, night waking does not affect their temperature recordings, so long as they get a 2 – 3 hour block of sleep before taking their temperature at the normal time.
If you wake within that final 3 hours of sleep, you may want to take your temperature then, as well as at your normal time. For example, if you normally take your temperature at 6.30 am but you wake at 5 am to go to the bathroom, you won’t get a 3 hour block of sleep before your normal wake time. So in this case, take your temperature at 5 am and then again at 6.30am and compare them. Use the temperature that is the most consistent with your other temperatures.
If you consistently wake at the same time within your final 3 hours of sleep, for example if your partner gets up for work, it might be best to move your temperature taking to this time, even if you go back to sleep afterwards.
