Tracking your morning temperature
Your morning temperature can confirm that you ovulated - useful if you're trying to conceive or just want to understand your cycle better.
"Morning temperature" (sometimes called BBT, short for basal body temperature) is your body temperature the moment you wake up, before getting out of bed. It dips slightly during the first half of your cycle, then rises by about 0.3°C after ovulation and stays higher until your period.
How to take it
- Take it at the same time every morning, before you sit up, talk, or drink anything.
- Use a thermometer that reads to two decimal places (look for "basal thermometer" or "BBT thermometer" - any pharmacy has them).
- Log it in Vernya under Vitals → Morning temp.
What it tells you
After three days in a row of higher temperatures following a stretch of lower ones, you can be fairly sure you ovulated. Important: morning temperature confirms ovulation after it happens - it can't predict it ahead of time in the same cycle.
Common questions
Quick answers to questions people often have about this topic.
Do I need a special thermometer?
Yes - a "basal thermometer" that reads to two decimal places. A regular fever thermometer isn't precise enough to spot the small change you're looking for.
What if I forget to take it some mornings?
That's fine. A few gaps don't ruin the chart. Just skip the day and pick it back up tomorrow.
Why doesn't my temperature show a clear jump?
Sleep changes, alcohol, illness, and shift work can all blur the pattern. Looking at the trend across a few weeks is more useful than any single morning's number.
Can I use a wearable instead?
Some wrist or ring devices estimate overnight temperature and can be a good fit if a morning thermometer is hard to stick with. Their numbers are different from an oral basal reading, so don't mix the two on the same chart.
