bbt to test for pregnancy

[lisa77]

Hi,

Ive just been watching some videos on fertility friend, and after watching them, Im sort of thinking, that you could use your bbt to tell if pregnant..

from what Im gathering, the day after you have ovualated, your temperature spikes, and stays up, but if you are pregnant, it stays around that temperature for the entire pregnancy... and if you are not, then you can tell by your body temperature coming down ..

or am I totally reading this wrong !

I just thought it would be good if you can.... think of all the money on wasted pregnancy tests !

oh to add, it looks like from the charts that I have read, you would be able to tell from day 9 to 10, if you are pregnant as your temperature has dropped around this day

That's soooort of right.

Your temp gets elevated and stays elevated your whole pregnancy. However, along the way there are dips and spikes and the like. There's really no way of knowing for sure if a dip or a spike represents the beginning of a trend (ie, temp falling or rising) or if it's an isolated temp unless you continue temping. And also, just because you have high temps does not mean you are pregnant- just like low temps doesn't mean you're not. There are lots of different temp patterns, it all depends on how they correlate with other signs such as HPTs and CM and the like.

Not necessarily.. Usually my temp drops the day before or the day af arrives,, it will def tell you that af is coming.. But if your temp stays elevated past when af is due, then it's likely u could be pregnant and could test,, but if you want to know earlier you'll have to test..

Like others have said this is kind of true. Have a look though at some pregnancy charts on FF they are all so different.
With my DD my chart was far from perfect rose slightly for 3 days after ovulation, dropped for 3 days and then rose again all barely above the cover line then I got a BFP and it dropped again for 2 days, I stopped temping after that (may have showed a rise again if I kept charting though).
I guess lots of people may have better charts. A good indicator is no period and temps rising.
My temp always falls day before or day of AF too.

Hi Lisa... I had read that if your temp stays elevated for 16 (or was it 18?) dpo, chances are good that you're pregnant. Unfortunately, ovarian cysts can also cause your temps to remain elevated. I learned this the hard way before we were even officially ttc when I was trying to get the hang of temping - af arrived as scheduled but with elevated temps. What a disappointment!

your temp has to spike 2x. It makes your chart triphastic. after OV it goes up and stays above coverline until just b4 AF itll drop. OR itll go up again and that could mean your pregnant. Here was my thriphastic chart showing I was pregnant

Not all triphasic charts mean pregnancy and you can be pregnant and not have a triphasic chart too. My charts have never gone Tripasic during a pregnancy.

Here is what Fertility Friend says

A triphasic chart can be promising, however, because progesterone levels generally increase after implantation (7-10 days past ovulation) in conception cycles, and sometimes this results in a triphasic pattern. If your chart shows a second significant thermal shift that begins 7-10 days past ovulation, Fertility Friend will indicate a triphasic pattern in the Pregnancy Monitor. A triphasic chart, however, is not a definite sign that you are or are not pregnant. It is just increasing your probability if you also have well-timed intercourse. Likewise, you can be pregnant and not have a triphasic pattern. Like all signs of possible implantation or pregnancy, you can really only speculate about it once a pregnancy has already been confirmed.

I have actually lost faith in my charts showing pregnancy cause i have had some fabulous looking charts that end in AF.

I have heard too that 18dpo of sustained high temps means a very high likelihood that you are pregnant. Never knew about oviarian cysts though. That is interesting, thanks for that info ButGoodie.

Thanks for all the comments

Goes to show, sometimes you can read a lot into things !

Wouldn't it be great if the egg stayed waiting around like sperm does ! Giving us a higher chance of pregnancy instead of a 1 day window... !

I started brown spotting last sunday, and it was literally a spot or two when I wiped, when reading FF it said, to not count this as the first day, only count when its red... which happened on the wed this week.
so I inputted the first day of my period (which I thought would be wed) and it showed me my likely days on ov, then I inputted the day that I was spotting, and it changed my days... talk about confusing ! its doing the exact opposite of what it told me to do!

Luckily I have an ovulation kit, so I will be using that and I will have a better indicator (fingers crossed) on which day I should be ready.

I honestly don't know how you all haven't lost you mind, ive only been at it for 1 month... !

Baby Dust to you all !
