Winter is here: will it affect my basal body temperature?

Generally speaking your body should not be affected, given that you have normal bedding (what you usually use) and room temperatures at home. Your body is great at maintaining a regular temperature and will adjust to the cold weather!

With Natural Cycles it is important to measure your basal body temperature in your mouth and underneath your tongue. By closing your mouth and breathing through your nose you can avoid external factors like room temperature influencing it. This is why measuring your temperature on your skin or in your ear is not accurate enough to use with the app.

We also want to point out that electric blankets and heating pads can have an effect, so keep an eye on your temperature curve when using these. Winter is also the time of year where a lot of us get sick, so if you feel unwell and your temperatures are much higher than usual be sure to disable the measurement until you feel better again.

Happy Cycling!

Brand new graph design and features

We hear you, Cyclers! We appreciate all the feedback we have received on the app! We’re happy to announce the release of the new (and improved!) graph. Read all about the exciting features, below!

 

Access the graph whenever you want!


To view the graph, turn your phone to landscape mode and the graph will appear! Just make sure that the portrait orientation lock is off and you’re good to go.

Lines between the temperature values

 

You’ll notice the new graph now has lines between the temperature values. This is to make it easier for you to see the (possibly) slight fluctuations in temperature.

 

Graphs

 

 Scroll through one, three or nine cycles

You can now see one, three or nine cycles at the same time. Also you can click on the ‘previous’ button and see previous cycles, one at the time.

See an estimate of your next temperature graph!


Now, you can see an estimated forecast of how your next temperature curve might look. This is a great feature for those of you who just started measuring.

New safe sex icon and changed place of the icons 

 

Print
Now there is an icon for safe sex too, so you will see it in your graph whenever you log a protected intercourse. Before, the icons for intercourses were seen below the temperature chart, but now they are above it. The reason why we switched places is because sometimes the low temperature values could be hidden by the icons, and now you can clearly see both.

 

Let us know your thoughts and keep the feedback coming. We are listening! Also thank you for all support!

I miss the red and green days!

My favorite color is blue. I like having everything in blue. If I could decide all of the styling, I would have made everything blue on the NaturalCycles website.

It doesn’t work, though, since our users usually have red (fertile) and green (non-fertile) days and the styling of the web site changes accordingly.

Blue days in NaturalCycles stand for pregnant days, and as I am currently half way through my pregnancy, I am in the middle of an ocean of blue, blue and yet more blue days. In principle I should be very happy about all the blue, but to tell the truth, I really miss the red and green days.

Red and green days - NaturalCycles

I guess what I miss is really the diversity. I miss the excitement of ovulation day, after a period of red days, knowing that green days are around the corner. The green days used to feel special, a luxury, something to treasure. Now every day is the same and waking up to check what temperature I have does not have the same kind of meaning as before.

I also used to enjoy the subtle changes from cycle to cycle, as my body had been longer and longer without hormones and as NaturalCycles received more and more statistics from me. Will the yellow days eventually turn into more green, as they usually do with more data?

What is more fun now, is of course to track the development of the baby, how the movements are getting stronger every day and how the belly is growing.  But I do look forward to getting back to feeling how time passes by going from red to green and green to red.

When to measure and when not to measure

One question about tracking the basal body temperature for natural family planning is when to refrain from measuring. If you are clearly sick and have a fever, NaturalCycles will detect your temperatures as abnormal and automatically exclude them. However, if you are just feeling slightly under the weather, or have been partying the day before, or simply sleeping significantly more or less than usual, your temperature measurement for that morning could be slightly shifted. This is not at all “dangerous” and it will not make you get green days during your fertile window. It could however cause you to get less green days as NaturalCycles provides the same level of safety for all types of temperature fluctuations.

It is therefore better to refrain from measuring for days where you don’t follow your normal rhythm. Especially if you haven’t just started measuring your temperature. NaturalCycles uses all of your data data from the first cycle you enter, when it analyses your new incoming temperatures and therefore, after three cycles or so, statistics become less crucial. Myself, I have now used NaturalCycles for 500 days and I have meanwhile acquired quite some statistics. I therefore only measure on days where everything is according to my normal every day schedule. For example, before this morning (Monday), I did not measure since Wednesday (see chart). Thursday was the Swiss national holiday so there was some drinking involved for both Wednesday and Thursday evening. Then, during the weekend, I slept considerably longer than usually. Since my data are not limited by statistics anymore, and I am not yet close to ovulation, it is fine for me to skip those 4 days in a row. I you have a look at my chart below you see that there is a nice line until today, probably since I skipped the days before where I’d otherwise get elevated temperatures due to sleeping in/alcohol.

Measures - NaturalCycles

I will summarize some useful rules of thumb that you could adopt for optimal temperature tracking:

  • For the first 3 cycles, try to measure as often as possible
  • For the 5 days before and after expected ovulation, try to measure almost every day
  • Outside these two scopes try to at least measure 4 mornings/week, but strictly don’t measure if:
    1. You get more than 2 hours of more/less sleep than usual
    2. You wake up more than 3 hours earlier/later than usual
    3. You drank more than usual the evening before and you feel the alcohol the following morning
    4. Skip the first morning after having traveled long distance to a different time zone
    5. You feel ill or have a fever

If you apply these guidelines, you should get nice temperature curves. There will of course always be some fluctuations, which cannot be avoided, but that’s normal and nothing to be concerned about. You should also try to avoid first measuring and then deciding whether to use the temperature value or not. That might bias your chart to look like you want it to, rather than what is actually correct.

When you have to measure the LH hormones with ovulation tests (OPKs), you don’t have to worry about more/less sleep or alcohol.

You should however try to not drink any liquids and not go to the bathroom at least 2 hours before measuring, preferentially more than 4 hours. Best is also to avoid taking the test in the morning. This might sound confusing, as pregnancy tests are best taken when you wake up, but the LH surge often starts in the morning, so if you take your ovulation test then you are more likely to miss your LH peak. Of course, if you don’t find a good time during the day to avoid liquids for a longer time, then the morning is to be preferred.

Happy measuring!
