With the Clearblue weeks digis it's all a bit approximate. I think the weeks are meant to be read as from conception, but the different readings are triggered by different levels of HCG, so 1-2 weeks is based on 10miu, 2-3 weeks is based on 153miu etc. They can vary a bit from woman to woman, pregnancy to pregnancy and of course urine dilution, hence why it's a bit approximate.
I'm now 9dpo and of course I got a BFN. I hate this stage in my cycle. It's like I have the devil and angel on each shoulder:
Angel: 9dpo is meaningless- too early to count yourself out. You DTD on O-2 and one sperm is all it takes. Maybe Dry January and the cough medicine you've been taking for your rotten virus will have made all the difference. Plus Sod's Law - Oasis in September wouldn't it ideal if you've caught this cycle.
Devil: it's been 37 cycles of nothing. Why should this one be different? Yes, you DTD on O-2, but you've never had any joy this time on the cycles when you managed O day itself, O-1 and/or the entire fertile period, so why get hopeful about this cycle?
I wish I could squash the Angel tbh. I hate the false hope against all likelihood/experience...
