Question about BBT.... please answer?

Question

I get up roughly at the same time daily now with work and routines. I was wondering how far off can you take your BBT.

I mean if I wake up early or late... how does that affect it?

References would be great, but experience is nice too!

Thanks.

I talking about maybe a 30 minute difference.

Answer 1

Your temperature reading can rise up to 1/10 of a degree for every half an hour taken later than normal or fall 1/10 of a degree for every half hour taken earlier than normal. To get an accurate chart, it is crucial to take your temperature as close as possible to the same time everyday. If you normally get up during the weekdays at 6:00 AM try and take all your temperatures at this time. Weekends can be tough....we all like to sleep in, just remember that each temperature that is not taken at the normal time has to be adjusted (using the 1/10 for every half an hour rule) which will get you close to what your temperature should have been. Always log the time your temperature was taken each day and make a notation if your temperature has been adjusted.

Good Luck!

Answer 2

I've read that you're supposed to take it at the same exact time - I actually set my alarm even on weekends and take my temp, then go back to sleep! But the first month I tracked my temp I didn't bother doing it at the same time, I just did it whenever I woke up (which could be a few hours later on weekends than weekdays). I didn't notice any effect on my temps - that first month looks just like this month, for the most part.

Answer 3

From what I remember from when I was doing it, its important to do it at the same time every day, after at least 4 hours of sleep. Obviously, if you woke up earlier than usual one day you wouldn't wait for an hour before taking it, you'd want to do it at the time you woke up.

I think once you get the hang of it over a couple of months you start to be able to tell when to expect your temperature to rise and its easier to identify those times when it may be off due to user error (deviating from usual schedule).

Edit: 30 minutes isn't really going to make a huge difference, I was talking more about hours of difference.

Answer 4

I have always used fertility friend- if the time I took my temps by were more then 1/2 off- I'd discard the BBT for the day.

Answer 5

Interrupted sleep can unquestionably impact temps for some human beings. For others, it would not look to impact it lots. It took me some months to truly get the carry close of my physique jointly as temping. so some distance as which temp to apply, it may count number on which temp became closest on your usual temping time. If neither one is close on your usual temping time, you could regulate it .05 in step with 0.5 hour (to a max of .15). This has continuously labored for me. that's addressed in the e book "Taking cost of Your Fertility" via Toni Weschler. in case you have not have been given it, I extraordinarily propose it! good success and infant dirt to you!
