    Does it matter where I take my temperature? I will follow the directions for the thermometer (i.e. take temp via mouth, etc.), but is one place on my body more accurate than another?

    Hey jomo80, Most women take their temperature orally, but it's also okay to take it vaginally or rectally. It's not recommended that you take your temperature in your ear or under your arm, as doing so may not give you an accurate reading.

    Whether you take your temperatures orally, vaginally, or rectally, you should always take it in the same place throughout your cycle. If you do take your temperatures vaginally or rectally, keep in mind that your temperatures will be higher than if you take them orally. This isn't a problem so long as you consistently take your temperatures in the same place.

    Does the nexcare thermometer that you recomend measure up to 0.01 in Celicius?

    Hi Ruby, Unfortunately, the NexCare thermometer has been discontinued. We're currently looking for another basal thermometer to sell in our store - for now, we recommend this one (which does measure to .00 in Celsius).

    Can you use a regular digital thermometer? Can't find an affordable bbt anywhere.

    I ordered a BBT last week (when I got my Implanon taken out). I just tracked it and it says it won't be here till November 20!!! What else can I use? I have a temporal thermometer. Or does Walmart or Walgreens carry any good ones?

    Arodsgirl - many women find that a regular digital oral thermometer works fine for charting their BBTs. However, if you chart your temperatures for a few cycles and don't notice any patterns, you may want to get a BBT thermometer, which tend to be more sensitive. 

    Katy - Unfortunately, temporal thermometers are not sensitive enough to record BBTs. Walmart and Walgreens usually have BBT thermometers, and though we haven't found a drugstore thermometer that we particularly like, you'll probably be able to find one that will do the job until you get the thermometer you ordered :)

    How can I tell if my thermometer is accurate. I have the geratherm basal digital. I took three temps in a row and they were all different.

    Hey gaelyn, because your temperature can start to change shortly after you wake up, taking your temperature multiple times in a row will probably give you unreliable temps. Try recording the first temperature reading you take each day in the app and see if you can notice a pattern.

    Do you have any experience or opinion regarding Terumo's Woman C?

    Hi Maria, thanks for contacting us!  I'm afraid we don't have any experience with that particular thermometer, but as long as it accurately captures your body temperature, it should work for fertility tracking.  If you give it a try and you have any thoughts on it, we'd love for you to let us know!

    Hello, I've been using just a regular thermometer and the temps are a lot lower then I thought they would be. It's a week before my period. Any

    idea why? I'm have some symptoms of pregnancy but the temps are confusing me.

    Hi Julie, thanks for contacting us! I totally understand how confusing it can feel when your body isn't behaving as expected - I hope I can help you.  Did you have a sustained temperature shift this cycle?  As long as your temperatures at at least .2 degrees F higher than the temperatures in the earlier in the cycle, chances are you've ovulated.  Not all women have super pronounced elevated temperatures, but it only takes a rise of .2 degrees to be considered a temperature shift.  So if your post-ovulatory temperatures are even .2 degrees higher than your pre-ovulatory temperatures, you have nothing to worry about!

    If your temperatures aren't staying high or didn't rise high enough, there is a possibility that you might have a progesterone deficiency or thyroid issue.  If you're concerned, you may want to get this checked out by your doctor just to rule out the possibility of any complications.  Let me know if you have any questions about this.  I'm also happy to look over your chart if you'd like me to - just send an email to feedback@kindara.com and I'll get back to you as soon as I can.  Thanks!

    I am using the Geratherm BBT Thermometer in Ferenheit but it measures to the hundredth of a degree (no option to measure to the tenth). I know you said to measure to the tenth of a degree for Ferenheit. Is it ok to measure to the hundredth? Or should I be rounding up or down and just record to the tenth?

    Hi Marshalay, thanks for contacting us!  You can measure your BBT to the hundredth if you want to, but it's not necessary to do so to detect your temperature shift (so you can round to the tenth if you'd like).  Whether you choose to chart to the tenth or the hundredth, you can change the decimal options in Kindara by tapping More, then Settings, and then tapping either the .0 or .00 buttons.  Let me know if you have any questions about this!

    Hello,

    I have just started charting my BBT in the beginning of this cycle so it's still pretty new to me. I take my temperature with a basal temp thermometer before I do ANYTHING and at the same time everyday. This morning when I took my temperature it was 36.2 (which is a pretty significant drop from my previous 5 reads). I decided to retest right away and it was at 36.5 and then again and it read 36.7 which is closer to my previous temps. I am 4 days post of what I think is my ovulation) so what could be the reason behind this discrepancy? Which temperature should

    I note down? The three temperatures were backed up by my digital standard thermometer so it's not that something is not working.

    Thanks ahead for any help!

    Thanks so much for contacting us! I'm happy to answer your question :) In general, you should ALWAYS use the first temperature that you take in the morning, even if your subsequent measurements are different from the first one. This is to keep the conditions under which you record your temps as consistent as possible. If you start choosing which temperature to record, you run the risk of recording the temperature you "expect" to see, which could potentially bias you into recording more inaccurate temperatures than accurate ones.

    I hope that helps. Let me know if you have any questions about this!

    Would a regular thermometer give accurate results? I am awaiting the arrival of my wink and have been using just a normal thermometer in the mean time but don't want to continue if it's just going to leave me feeling disappointed (temping with a regular this month has made me feel I didn't ovulate)

    Hi! Can I use my regular BBT thermometer vaginally? Or do I have to get a special thermometer for that?

    Lauren

    Hi Nikki, thanks for your question! Regular thermometers are generally accurate enough to catch your post-ovulation temperature shift.  However, if you chart for several cycles and your temperatures continue to be confusing, I'd recommend trying a different thermometer just in case yours isn't working as accurately as it should.

     

    Hi meriemtm, most regular thermometers can be used vaginally, but it may be worth consulting the manufacturers' notes on whether your product can be used vaginally before you do so.  I hope that helps.

    This past month, after my temp shift, my BBT reading has been exactly the same. Seems odd to me that 5 days in a row it's the same down to the hundreds of a degree. Should I be looking for a new thermometer?

    Hi Flyer, thanks for contacting us! Hm, that does seem fairly unusual - there's always the chance that this happened by coincidence, but you may want to consider changing the batteries in your thermometer or buying a new one just to be on the safe side.

    My BBT thermometer goes to the hundredth. Should I round up when the temp is, for example, 98.38?

    Hi jentri, according to our experts, it's not necessary to record to the hundredth of a degree, but you can do so if you'd like!  At minimum, you only need to record to to the tenths' place (.0), but you can record with more accuracy than that if you want (.00).  Hope this helps!
