Lh test not registering positive on premom?

[Pennyroses]

Hi, so I have done what I would call a very positive lh test this afternoon. I scanned it into the premom app and it's saying low 0.3?! I had a only just positive one last night but it has considered that my peak at 1.39 but today's is clearly much darker. I'm pretty confused, has anyone else experienced this?

Today's test

Last night's test. Does this mean I'm ovulating today or tomorrow?

I wouldn’t rely too heavily on the app to be honest. It never seemed to give me a proper reading and according to the app I didn’t ovulate, yet I still managed to get pregnant so I don’t trust it.
It’s still good to take the pictures so you can see for yourself if the line is getting darker. Try to just judge it for yourself if you think the lines are getting darker and just use the app as a general guide but don’t fully trust it.
I believe that temperature checking may possibly be a more accurate way of tracking ovulation, but I’ve not done this myself.

Thanks, it's my first month using it and I can't say I'm very impressed by it at all, just makes it all so much more confusing that it already is!! Think I'll just stick to judging the tests myself as I usually do, that's been accurate enough for me so far!
