Temp charters, is my ovulation wrong?

[Tracking]

Hi,
Can you look at my chart and see if you think ovulation is marked wrong? FF marked it as day 23, my ovulation date on previous charts is day 16/17.
On day 17, I had small amount of brown discharge in my underwear which I assumed was ovulation spotting although I've never had this before.
Do you think it's possible I ovulated on day 20? I went away on day 18 and 19 and forgot my thermometer so I'm wondering if I messed my chart up and it's calculated my ovulation wrong because of this?
FF has pushed my period due date back by a week because of this. I was due on yesterday originally.
I'm still pretty new to this as I have been charting for around 5 months so any help would be appreciated

@Tracking I'd say FF is correct looking at that graph but missing two days isn't ideal in quite a crucial part of your cycle. If you're late defo take a test. If negative, you've probably ovulated later as per the chart. You're v likely to get a positive if you are indeed pregnant if you ovulated around day 17 and are a day late.

@FlyOnTheWall89 I know I was so gutted I went away and forgot the thermometer at such a crucial time.
To be honest, I'm just hoping it was wrong as had limited time to dtd as partner was in and out of town . If I ovulated at my usual time of day 17 then I'd still be in with a chance, but if it was indeed day 23 then I think I'm out this month as dtd 5 days before ovulation 😔
I will pop out and grab a cheap test but I'm not hopeful.
Thank you for replying

I don't think it's possible that you ovulated on day 20 per the temps, as days 22 and 23 are still quite low. Tbh I'm not even convinced CD23 was ovulation day and suspect you ovulated on CD26.

@Juno231 that's strange you say day 26 because if I remove my ewcm from day 22, it moves my ovulation until day 26! But its the dotted ovulation line rather than the solid that comes up on day 22 right now. Either way, my period still isn't here and I'm not expecting it until end of this week minimum.
I don't think day 26 as I didn't have any ewcm by that point. Very strange cycle this one!
I stopped temping now for this cycle as its driving me insane analysing 😔
Thank you for replying though.
