What's the best thermometer for tracking BBT?

If you have a ton of money - BabyComp.

But if not, here are a couple good ones:

You can buy really cheap pregnancy tests from that website too!

Make sure you take your temp at the same time every morning and before you even get out of bed.

Stores like Target, Wal-Mart, possibly Walgreens, etc have their own store-brand thermometers. Those will work fine and be more affordable.

The one I use is a Target brand one. Just make sure it says "BBT" or "Basal" on the packaging. Basal thermometers all measure to the hundredth of a degree and take more time calculating the temp to be sure, regardless of how much you spend.

Helpful features you may want to look for:

-- Last temp recall (My under-$10 Target brand actually remembers 4 previous temps. Didn't come with any instructions on how to use this feature, but I figured it out on my own.) The reason this feature is great is that I temp at the same time every morning (as you should), even weekends. Except on weekends, I go right back to sleep afterward, often without writing it down. Hard to remember the temp after a couple hours more sleep.

--Backlighting. My thermometer doesn't do this, and overall I'm content without it. However, you may find it desirable to have a thermometer that lights up so you can read it in the dark without having to turn on a lamp or angle a cellphone at it. OR, you can just rely on last-temp recall to read it later and thus not need this feature.

Walmart actually sells a BBT thermometer for under 10 dollars. But it really shouldn't matter.

all i understand approximately charting your temp is you ought to do it mutually as in mattress so as quickly as you awaken by using fact your temp is what it would be yet as quickly as you initiate shifting it differences so it could't be precise, and from what ive study the temp is going up once you ovulate? so whilst it is going intense you have already ignored it yet in case you have been charting it for a mutually as then the day till now you should be waiting to declare oooh yeah thats what it gave the impact of the final 2 months till now i ovulated, or some thing like that besides i study it, its why ive not at all relatively troubled to do the temp bit lol

I just bought one from Walgreens.

I don't think it matters what brand, as long as you use the same one every day.

i bought my from rid-aid
