Confused! When do you count 1DPO from?

[RMarieClaire]

Got peak clear blue OPK CD23 morning, but I didn't track BBT or have obvious ovulation symptoms so I suppose I could have ovulated on CD24. Now on CD33 but confused whether that's 10DPO or 8/9DPO. Everyone always seems so sure so wonder if I'm getting it wrong.

Got a BFN yesterday on CD32 and trying to work our whether i have any hope or if I need to move on this cycle! Also only dtd CD18, 19, 20, 23 & 24, so in my gut know we've blown it this month. 😢

I would say you're 8/9 DPO and that if you ovulated on CD24 then you DTD on all the perfect days for it.

Good luck, you definitely could just be testing early.

Thank you @curiosity101 - I'll allow a glimmer of hope then. I think I'll try not to test for a few days though. Those BFN are a real punch in the gut!

I've bought a thermometer so I can track BBT next month and be sure.

I use the fermometer app, it tells me how many days I am. Ovulation day is the day after your first peak opk reading I think, that's what my app says.

Thanks @Nottherealslimshady - will give that app a try. I use Ovia and it's good for some things but not great with irregular cycles.

So would you say that this is likely/possible: Peak CD23,
ovulated CD24
1DPO CD25
Meaning I'm now 8DPO?

Imagine AF will come tomorrow then I'll track BBT and switch apps

Oh no i think I'd be 9DPO, so not sure I can hold hope after all. Boo.

So peak CD23, ovulation CD24, 1dpo CD25, 9dpo CD33. For irregular cycles I'd recommend using fertility friend app aswell, it's been the one that had adjusted my cycle the most readily to new information. But fermometer really explains stuff well.

A BFN isn't very reliable at 9dpo tbh, fertility friend did a study here www.fertilityfriend.com/Faqs/Early-Negative-Pregnancy-Test-Before-a-Positive---Stats-Study.html

How long is your cycle? I've attached what first response say are their accuracy but a lot of studies have shown it to actually be less.
