Why did my cover line change?

Question

After ovulating my coverline was quite high and I was worried as my temps were below the line.
See chart below:

Then when I entered todays temperature my coverline completely changed.

I just want to know is this ok?
My coverline never changed with glow, still high with temps below the line.
I was wondering if this could be a sign of low progesterone?
Any advice would be greatly appreciated 😊

Answer

The second coverline looks right. It’s just FF changing it’s prediction realising it’s got it wrong.

Answer

I think the high coverline is correct, in part because I find most people have a coverline right around 36.4/97.4ish and haven’t ovulated unless at least 36,5/97.5. It does look like you ovulated but perhaps low progesterone. If it’s a one month thing, no big deal, if it happens frequently, see a gynecologist.

Answer

Thanks Jessica, I thought the first coverline was correct too. I just don’t know why FF suddenly changed. The low temps were confusing me and the only thing I could find about low post ovulation temps was low progesterone. I have been charting for 4 months now and never had temps below the line, 2 of those were pregnancies that ended before 6 weeks. I was wondering if I do have low progesterone and that is maybe why my pregnancies couldn’t continue. I’m going to observe for a few more months, I want to avoid pregnancy until I know what is going on with my body. Thanks for your help.
