    The first phase is called the follicular phase. This phase starts on the first day of your period, each cycle, and ends at ovulation.

    At the end of your luteal phase your temperature will drop and you will get your period.

    After ovulation is the luteal phase

    Does the temperature of the room effects your bbt?

    Hey there,

    The temperature of the room probably won't affect your BBT (unless there's a huge difference in the temperature of the room from one day to the next), but it may affect the temperature of your thermometer, which can give you an inaccurate reading. To prevent my thermometer from getting too cold at night, I keep it under the blankets (which also makes it easy to take my temp right away when I wake up!). At any rate, try to keep the temperature of the room you sleep in as consistent as possible.

    I took my temp when I woke up at 5am, but went back to sleep for 2 more hours.  I took my temp again out of curiosity.  Which is the accurate temp?  The first one was lower than the second by .8 degrees.

    Hey fsululu,

    What time do you normally take your temperature? I would say that the 5 AM temp is the more accurate one, as you need at least 3 hours of uninterrupted sleep to get an accurate BBT. But if you normally wake up at 7 AM, then the temp you took at 5 AM won't be very useful to you. After you fall asleep, your core body temperature drops, then gradually rises until you wake. So your temperature will be lower at 5 AM than it is at 7 AM.

    So, if you normally wake up more than an hour later than 5 AM, I would mark that day's temperature as 'questionable' in the app.

    Hope that helps :)

    I never sleep well. Can I use this method accurately at all? I rarely sleep 4 hours straight and often wake multiple times during the night. Any suggestions?

    Will sleeping very close to my husband affect my temps?

    Hey taylor.tyler.12 - if you wake up several times throughout the night, you should take your temperature several times, and record them all (as well as the time you took each temp) in the journal section of the app. Take your temperature when you wake up for the day as well. Then, look at all of your temperatures and see if you can notice a pattern throughout your cycle.

    gwilson20 - snuggling with your husband shouldn't affect your temperatures enough to throw off your charts. But, if you think it might be altering your temperatures, you can take your temps vaginally, which is thought to be more accurate for BBTs.

    I work night shift and sleep during the day. How should I track my BBT?

  • Avatar
    Courtney

    Hey darcikhill, it doesn't matter what time you wake up, so long as you take your temperature around the same time each day. So if you consistently wake up around 8 PM, take your temperature as close as possible to 8 PM (or whenever you wake up), and you should notice a pattern in your BBTs :)

    Do you round up or down with temps ? I was 97.49 today

    Hey kellycap123, for extra accuracy, you'll always want to round down. This is so you don't mark a false high temp and think you've already ovulated when in fact you may still be fertile. 

    However, it is possible to chart to two decimals with Kindara! To change your temp settings, tap the More icon in the bottom right hand corner of the screen, then tap Settings. Next to 'temp decimals', tap the .00 to change your settings. That way, there's no need to round your temps :)

    I'm coming off hormonal birth control (1 week before my cycle would otherwise start). When can I start taking my BBT?

  • Avatar
    Courtney

    Hey there, 

    You can start taking your BBT as soon as you want! Right after coming off hormonal birth control, know that your temperatures may not follow a clear pattern at first, as it can take a while for your cycles to regulate. However, some women WILL start ovulating right away - so only through tracking your signs will you know if and when you ovulate! 

    Even though you may not notice a pattern right away (especially if you're starting in the second half of your cycle), starting to track your temperatures now will help get you used to doing it every day. It can be hard at first to remember to take your temperature first thing in the morning...but after a while it becomes a habit.

    If you want to wait until your next cycle starts, that's perfectly fine, too! It's up to you :)

    Currently I am taking progestrone meds both orally and vaginally, would it be worth my while to track my bbt?

  • Avatar
    Courtney

    Hey there,

    It depends. If you're taking progesterone because you haven't been ovulating, and are taking it throughout most of your cycle, tracking your temperatures won't be very useful. If you are ovulating and are taking the meds in the second half of your cycle, tracking your temperatures will let you know exactly when to start taking them - i.e., right after the temperature shift occurs.

    I've been breastfeeding for 10 months and don't want to wean yet, I don't get a period & I am wanting to get pregnant. I have no idea if I ovulate yet and want to use bbt to find out. Does bbt work with breastfeeding and no periods?

    Hi there,

    If you don't have a regular sleep schedule yet, it will be difficult to notice a pattern with your BBTs. However once you establish a sleep schedule in which you wake up around the same time each day and after at least 3 hours of uninterrupted sleep, you should be able to notice a pattern in your BBTs.

    Right now, the most important thing to look out for is changes in your cervical fluid. Wet, fertile-quality CF means you are likely becoming fertile again. You may experience several 'false starts', or fertile patches of cervical fluid in which you don't actually ovulate. This means your body is gearing up to ovulate again, but hasn't yet passed the estrogen threshold necessary to release an egg.

    Hi,

    I have been using the chart just to track my periods, but am now adding BBT. I have a very low body temperature (97.5 in the middle of the day). Will this affect my charting? What sort of spike could I expect to see?

  • Avatar
    Courtney

    Hi there,

    If you're ovulating, you should still notice a rise in your temperatures, and the rules for the temperature shift are the same (your temperature on the day of the temp shift must be at least .2 degrees higher than the temp from the previous day, and at least .1 degrees higher than the temps from the previous 6 days).

    However, low temperatures can be (but aren't necessarily) an indication of a thyroid problem, which can affect your fertility. You may want to check with your doctor to rule out any thyroid issues.

    How many times a day should I check my basal temp ? Should I record it in the app everytime ?

  • Avatar
    Courtney

    Hi Carolina,

    You only check your basal temperature once - first thing in the morning, as soon as you wake up (BEFORE you get out of bed!). Try to take it as close as possible to the same time each day. If you take your temperature more than an hour earlier or later than normal, mark it as 'questionable' for that day.

    I know this sounds like a stupid question lol! But how do I know how long my cycle is?! My menstrual cycle is not always the same time every month and usually lasts about 7 says. So how do I accurately figure out how long my cycle is?! I saw the options like 28-38. Any info. Would help thanks! I am currently trying to get pregnant. Please help!! Thanks

    Hey there, 

    There are no stupid questions here :) The length of your menstrual cycle is the number of days from day 1 of your period to day 1 of your next period. Often, it won't be exactly the same from one cycle to the next - this is totally normal! Only through tracking for a few cycles will you learn about how long your average cycle length is.

    Is this possible to work on a woman who is not getting a period still after 6 months of being off of birth control. My doctor suggested waiting it out but my husband and I are so anxious. Thank you

    Hi there,

    If you're not getting your period, it means you're not ovulating - yet. You can certainly start tracking your basal temperatures and cervical fluid now, but you may not see much of a pattern yet. However, that doesn't mean it won't be valuable - when you do become fertile again, you'll know!

    Keep in mind that fertility charting is not going to 'work' in that it won't change what's going on with your body - rather, it will allow you to interpret what's going on, so you can know whether you're fertile or not.

    Hi. My bbt remains slightly high (97.5-97.8) during the first days of my cycle (while I am menstruating), then gradually drops down to follicular phase bbt (96.8-97.2) until day 20. Is that normal? Should the shift prior to day 1 be as dramatic as the ovulation shift?

  • Avatar
    Courtney

    Hey there,

    Some women will experience a dramatic temperature drop at the start of a new cycle, whereas others will have a more gradual decrease to their pre-ovulatory range - so yes, what you're describing does sound normal :)

    Do you use a regular thermometer? I've heard you needed to use a basal thermometer.
