I’m not TTC right now but went off the pill because I’ve always had wacky periods and I am finally reading Taking Charge of Your Fertility (at a friend’s recommendation) and I just want to see what happens with my cycles after basically being on the pill for, I don’t know, 8 or 9 years or so.
So, when charting your temperature each morning, do you have to use a special thermometer? I was planning to just use a regular digital thermometer that shows your temp to one-tenth of a degree. Then my friend shared an article about why you need to use a special basal body temp thermometer because it’s more precise.
So, what advice do the veteran charters have? Does it REALLY matter? What do/did you use?

@Miss PumpkinPenguin: I’m doing my first month of temping with just a regular 00.0 thermometer to to see if I’ll realistically wake up to take it each month before investing in the one that measures to the hundredth. Supposedly it does matter thOugh. If you’re looking to track the spike it may get missed if a .1 increase isactually a .19 increase because supposedly the regular ones don’t rOund up.

I bought a basal thermometer from Amazon – it was less than $10. I would definitely recommend it! Get one with a light, so you can see it while you are laying in bed.

As oracle said, I think people usually use basal thermometers. I know target sells them. I almost bought onon instead of the regular on accident once 🙂

@Miss PumpkinPenguin: Also maybe all digitals do this but make sure you get one that saves the last temp recorded. Then if you wake up to take it before you actually have to get up you can just pop it in and do the input later without sleepy head trying to remember the number.

@Miss PumpkinPenguin: Agreed with the PP’s.
I think a thermom to the tenths would be fine, but I am very happy that mine goes to hundredths. Specifically, because like SapphireSun said, there’s a big difference between .1 and .19. Either way, it’s good you’re temping, but I would personally recommend a BBT that goes to the hundredths. TCOYF recommends to the tenths, I think.

You need a BBT if you’re going to chart accurately. I got mine at CVS and it was less than $10.

I got mine at Target for around 10 bucks, I like it so far.

It needs to be 0.1 accuracy and regular digital thermometers only give 0.2 accuracy most of the time.
Another factor…it is usually very dark in the bedroom when I take my temperature (we have blackout curtains to block the sun while we sleep) and I know my regular digital does not light up like the BBT I have does. Also, my BBT beeps while it is measuring which is semi-annoying but also is reassuring as it is dark and that is the only way I know that it is actually turned on and measuring.
I also got mine on Amazon for around $10.

I used a regular thermometer, and it showed my temperature spikes just fine. My personal opinion is that BBT thermometers are a gimmick.
Here’s my chart from the month I got BFP, you can see my temperature changes just fine, having an extra decimal place wouldn’t have mattered:

I started charting with a regular fever thermometer and the chart that I got with that didn’t make any sense. I didn’t start seeing ovulation until I used a basal thermometer.

But you also want one with a memory that will store your temp, until you check it again. Such a lifesaver on the weekends when you want to sleep in!

Definitely go with a BBT. I wanted to test out whether it mattered what thermometer you used, so I used both at the same time for a few mornings. They did not give me the same readings and the BBT was more accurate.

You’re looking at differences/fluctuations in temp so a digital with at least one number after a decimal (i.e. 98.6) is good. If you can find a digital with two places after the decimal (i.e. 98.68) then you should do even better. And I say digital because I tend to have trouble reading and rounding the old fashioned thermometers.

I bought a BBT thermometer first that was 00.00 and since it was a little bit slower than a regular digital thermometer I tried to switch and not having that extra number really messed up my charts. If you have a very slight change in temperature you will miss it. But the BBT thermometers are less than $10 at a local drug store.
