Blazing positives still 4 days and counting ?

Does anyone know what it means when you have blazing positives for 4 days might be 5 as tonights one is a blazing positive too ! I have just took one now and its another blazing and that was with diluted urine!

I know people say you ovulate from the first positive and just count that one but I can’t help to think why are they so dark still , I always track my ovulation and the surge ALWAYS goes down after a day ... so this is very new and odd for me ...

does it mean I’m realising 2 eggs ? Is it that It’s struggling to ovulate ? Im just wondering why !

I have looked it up on the internet and most common is 2 days so I thought 4/5 days was a bit odd ? Thankyou in advance ! TTc baby no2 !
