Help me understand my LH tests please

[ohblahdeeohblahdahlifegoeson]

I'm back to tracking ovulation after a chemical pregnancy earlier this month but I'm not sure what my results so far mean.
I would have thought they would start off lighter and then gradually get darker but mine have gone darker (although not very dark at all) down to lighter.
Granted I've only tested for 4 days in a row now, CD8,9,10 and 11.

Can I expect them to start to darken up again in a few days?
My app tells me I should be ovulating in 3 days but I doubt that will be the case

You can absolutely expect them to darken in the next few days. Half of women have a surge that lasts less than 24 hours. Look at the dates of mine - they go from pale to strong very quickly! Keep testing 👍🏻

And another one 😊

Thanks @Decaffe, here's hoping!
