BBT chart help - low temp after ovulation?

[13lucy]

Hi all - just wondering if any BBT charters can help with what's going on since I've ovulated? Month 1 of TTC after miscarriage so naturally worrying about everything!

After ovulation my temp peaked to 36.71 a couple of days ago but is now down to 36.45 at 3 DPO. I did have a weird spike this cycle on CD8 after my COVID vaccine.

In comparison, my last chart peaked at 36.55 and then sat at about 36.6 until AF arrived.

Is this normal? Could there be an issue with hormones? Any advice would be much appreciated!

@13lucy if your temp doesn’t stay up after ovulation it’s usually a sign of low progesterone but there are a lot of factors that can affect your BBT as I’m sure you know so I would suggest giving it a couple more days before worrying to much (I know easier said than done), if it goes back up then it could have been down to a variable. If it stays down then that would be something to look into x

Here’s mine usually 2dpo is already very high but this month my temps went up very slow and ovulation hasn’t been recognized. Pretty sure I ovulated Wednesday so I’m around 5dpo. Wait a couple of days and see what happens.

I often have a drop around 4dpo and then it goes back up. It’s pretty normal, so if yours goes back up I wouldn’t worry. See what happens over the next few days.

Like this, for example

Thanks all, that's been really helpful! I thought I'd wait a few days before reporting back and my temp did rise again so hopefully that's a good sign? Went up to around 36.65 for a couple of days and now at 36.59. No idea whether this cycle will be the one or not!

Was it the one?

@Plumchumm nope! 5 cycles on and still no luck 😢
