BBT temping accuracy

[Abombflower]

Hi,

I am temping for the second month and my chart is very up and down. I think I am 2dpo and from looking at my chart if I have a higher temp tomorrow this should confirm this… I think.

But I’m confused about the accuracy of temping as I took my temp this morning (I do it first thing before I get out of bed) and I recorded the temp and then for the hell of it I did it again a few mins later (still in bed) and the temp was different. Obviously not much but enough to change the graph.

Apologies if I’m just being stupid (new to all this!) but I did read that BBT temping is not considered all that accurate scientifically because of so many variables but all the charts I see look perfect and not like mine which looks like the Himalayas😅

I find that mine changes based off so many different things, for example, when the weather gets colder my BBT is overall lower, it’s also affected by things like sleeping with my mouth open 😂
Ive been doing BBT for well over a year now (not ttc that long) and I’d say this is my first cycle when it looks quite consistent, I’m not sure if coming off the pill had an impact on that though. With my first few months it definitely took longer to find ovulation with BBT though x

I'm a very light sleeper and wake in the night so for me bbt has never been accurate. Lightly dozing before waking affected my temp, as did wakes in the night. I just tracked LH instead and was fortunate to get pregnant three times straight away. So temp tracking isn't really necessary if it's not working for you.

Mine is up and down like a mountain range but I can see definite rprisexafter ovulation.

Rise after

Hi, which app do you use? Mine zigzags too but when I ovulate there was a definite increase.

I used fertility friend. I also tried to record the temp in the same 30minutes window, but not always. I didn’t set an alarm it was just when I first wake up. I have attached two of my graphs to see my zigzag and the noticeable change after ovulation too. BBT for me worked really well and was accurate overall for ovulation

Thanks for sharing! This is mine, got the cross hairs added this morning which was good to see as I have PCOS and was worried I may not be ovulating. My temp did stay high last month until AF arrived so hopefully will this month (and get a bfp!) too x
