CPAP and basal body temp when TTC

This may seem like an odd post to some. I appologize in advance if any of this is TMI.

I am newly married, and already have one daughter who is 5. We have gotten off all birth control and are now working on baby number 2. I am temping to make sure I am actually ovulating (as my dr asked me to). The question I have is...would an oral temp be acurate after using CPAP all night? For those who do not know....you have to take your basal body temp right upon waking before you move or get out of bed. It is a more precise measurment than you get with a regular thermometer...because you temp while ovulating rises sometimes just a fraction of a degree.

So now I am wondering if I should try under the arm rather than oral. Has anyone else done oral BBT temping while on CPAP?

Don't know about the CPAP part and oral, but ...

Low body temp is one "symptom" of sleep deprivation. So you might have a different basal temp when getting adequate sleep - and no desaturations - with CPAP, than prior to using CPAP.

I know years ago one osteopath had me measure my morning temp to check for hypothroid. My body temp was consistently low, arond 96 degrees. Unfortunately the thyroid meds didn't help me at all.

I realize now it was a symptom of my sleep apnea, not hypothyroid! I wish I had known that at the time, or that he had,. I could have started treatment about 7-8 years earlier than I did!

Good luck.

I don't KNOW, but I don't see why CPAP would make a difference in your oral temperature. But if you can't move before temping, you'd still have to get the mask off, turn off the machine, get the thermometer and then temp. (Funny how little I remember about this, considering I did this myself...not with CPAP though). I think under the arm temperatures are very unreliable. But wouldn't using those ovulation test kits be easier and more reliable, albeit more expensive?

We are using the ovulation predictors as well. The doctor asked me to temp...so I am. I have heard you can actually do temping vaginally...but that just seems messy.

Well, not compared to rectally, I suppose.

Well, hello there. Good to see you in this neck of the woods. I notice you list a nasal pillows mask. Seems it would be more of a concern with a full face mask, considering mouth breathing and humidifer temperature. You probably don't want to have to do this for too many months, but if after a month you see too many unexplainable fluctuations, you could switch to vaginally. At least that would remove the unknown factor from your equation. Best wishes on on your growing family.

what if you used one of those digital ones that goes in your ear?

I wish I could use an ear one. But bbt thermometers are made to be more sensitive. Guess I will try it for a few months and see how it goes.

I seem to recall this is how my ex did it...back in the day. Whats to mess? Your only checking temp right?

Consider asking your doc but I'm willing to bet, this would be the preferred method.

btw - welcome back to the party. Oh and keep practicing one day you'll get it right

I wouldn't think it would change your temp that much if at all. What you are looking for is changes in your temp to see when you are ovulating and I would think you would see those changes even if cpap changed your temp. If you use your cpap consistently with the same hunidifier settings for that period of time you are taking your temp, I think you would still be able to detect that change in temp when ovulating. Now, this is just my opinion, but makes sense to me.

Yes this. I did this too for my youngest and it is the change in temp not the actual one. My temps were different from my partners' but the pattern was there (actually hers wasn't always there so we went with me instead). Besides even if you mouth breath a lot, the thing is under your tongue anyway.

If FFM I would just rip it off and put in the thermometer If it doesn't turn off automatically (mine does) then just let it blow until you finished taking your temp. Or let your partner turn it off and hand you the thermometer.

You can also increase basal metabolic temperature by adding coconut oil to your daily diet.

That is not quite what she is looking for - raising the temperature will not insure ovulation but ovulation will raise the basal temperature.

I'm misunderstood ... fairly normal for me.

As with most everything concerning our body, it comes down to managing hormones.

Leptin is produced by our fat cells and induces a response by our endocrine system as well as our brain. Leptin levels affect our metabolic rate via receptors in our brain and endocrine system, hence ovulation is also affected by metabolic rates. The body prefers to optimize reproduction by staying alert of the body's metabolic status (ie. is there sufficient energy storage to carry preganancy to term?).

Coconut oil is a medium chain fatty acid. When medium chain fatty acids are introduced into the blood stream, the brain and endocrine system leptin receptors become more sensitve to leptin levels. The body begins to think that it has plenty of energy and can increase the metabolic rate (which includes increase in body temperature) -- and thus the body senses that it is capable of successful reporoduction; triggering a hormonal shift agreeable for reproduction (ie. ovulation for women).

Oh, I remember those days. I did BBT's for about 2 years when TTC. Miserable--sometimes I'd fall back to sleep with the thermometer and it would fall out of my mouth. It was never very helpful in my case because I wasn't ovulating, just annoying. But, when you really want to have a child, you put up with many such annoyances.

Seems to me a few years back I saw digital ones marketed specifically for BBT and they also recorded the data so you didn't have to keep those charts, either. In this computerized age there has GOT to be a better way.

If you use the CPAP consistently, your body temperature may change, but you should still be able to spot the spike if you are ovulating. The key is consistency in using the CPAP and in taking your temperature.

I still question how reliable and useful this is. Some people use BBT as a birth control method--they are often called parents.
