Bbt lower LF so not pregnant?

[Nissalandy]

Hello ladies, want to ask a question about bbt and pregnancy.
December last year I was pregnant (wich unfortunately became a miscarriage).
At 2dpo my temp went up to 36.8 celcius and the rest of the LF and later on my bbt stayed above 36.9 celcius.

Is the same rise in bbt likely to occur in following pregnancies?
in other words is this pattern of bbt rise an indicator of pregnancy?
or is it possible that the next pregnancy has a different bbt rise?

sometimes I wish I never started measering bbt, because now I know at 2 or 3 dpo whether I’m pregnant or not.

Hope to get some answers!

No, you've got it wrong. Your BT will rise at that point whether you're pregnant or not. But if you're not it will then fall a day or so before your period as your progesterone levels drop. If you're pregnant your progesterone stays high and you don't get a drop and don't get a period. There is no way of knowing if you are pregnant at 2dpo, your body doesn't even know at that point.

Yes but my bbt rose to higher ends wirhout hitting the 36.60 or 36.70 range. In my non pregnant cycles temp post ovulation bounces back to 36.60, 36.70 something or 8.
But in my pregnant cycle it never came beneath 36.9.

I didn’t know I was pregnant back then at 2dpo, but looking back my bbt rose at 2dpo and never came beneath 36.9 after that.

I wonder if a next pregnant cycle will show the same rise, or if there is a possibility that the rise will be later in the cycle or around the day of menses

I mean there’s not really any way to know what your temps will do later post ovulation. But the 2dpo thing is irrelevant because as the PP said even your body doesn’t know it’s pregnant yet at 2dpo so it was likely just a blip. Everyone’s temp rises after ovulation so yours was likely just higher that month. I charted my BBT for years and some months it did odd things and rose or fell more than others. The only thing it did when I was pregnant was rise even further at about 12dpo. I had never got above 36.8 and it went to 37. I tested that day and it was positive. I really wouldn’t get into the mindset that if your temp rises 0.1 or 0.2 degree more than usual at 2dpo that you’re pregnant. You’ll likely end up more stressed and upset thinking you’re miscarrying if your period comes on time. Maybe stop BBT charting if it’s going to cause a lot of stress. All it really does is confirm when you have already ovulated. OPKs tell you when you are going to so are more useful for conceiving anyway.

Yes, but I’ve read more stories of bbt from women who were pregnant that cycle which went up very soon post ovulation, and so did mine.
I don’t understand how this can happen so soon, because you would asume that bbt goes up to the 37 range after implantation.

I’m not in the mindset you described, but more in one in where if I see lower temps, like 36.6 or 36.7 in LF I’m already in a mood in where I “know” that again I’m not pregnant.
This feeling is nit helping me at all, because it makes me very discouraged untill the fertile week has arrived.

I sometimes think it’s better if I stop bbt, but the thought of that makes me even more anxious..

You're getting way too obsessed with BBT. It can be used as a great tool to confirm ovulation, and to see it remain high when period is due is nice, but looking at exact temperatures is going too far.

Maybe take a break from BBT for a cycle?

I just want to know if the rise in BBT is the same with every pregnancy in the same woman.

Obsessed is a big word, I just want to know if I’m pregnant or not two weeks is a long wait

But at 2dpo you aren’t really “pregnant” anyway yet. Every woman would love to know early if they are pregnant. If there was a correlation with temperature like that that was standard it would be well known.
Even once women are pregnant there is no guarantee they will even have the same symptoms for each pregnancy. I’ve been pregnant three times. All totally different early symptoms.
I also had odd months with my BBT (I charted BBT for YEARS) as I said previously. Odd spikes and dips. A few times it almost went triphasic around 10-12dpo, but no positive tests and period arrived bang on time. So I wasn’t pregnant.

Two weeks can seem like a long time when TTC, but really it isn’t. Searching for a way to know at 2dpo really isn’t going to help unfortunately.

The rise in BBT after ovulation is simply because the corpus luteum is producing progesterone in anticipation of a pregnancy to support, after the egg is released. It doesn't know if the egg is/will be fertilized or implant.

So in a simple answer, no, at 2dpo you cannot say if you are pregnant based on BBT.

If it stays high when your period is due then possibly.

As above. The rise isn't due to a fertilised egg. You need to understand why it's happening, as it's not related to pregnancy - it happens because the egg has been released and the corpus luteum (the empty follicle) is producing progesterone to maintain the womb lining in anticipation of a fertilised egg. So it will fluctuate marginally whether you're pregnant or not.

I understand, so technically I still have a chance of being pregant this cycle.
asince bbt fluctautes for al kind of reasons.

Well, I took your advise and I quit bbt measering. I feel quite more relaxed and I’m almost at the end of the tww.
I still wonder wheter I could be pregnant or not, but I’m not obsessed in a toxic way.

Stopping with bbt charting saved my sanity, now hopefully we all get pregnant rather sooner then later 🤗

Good on you. BBT is an absolute waste of time.
