I’m super late and idk what is going on.. never been this late!

I know it’s just a little bit on the pregnancy test, do you think it’s just starting or invalid?? I’ve had previous tests (this brand) start off like this, then turn into a positive so I’m not sure what to think...

I also usually get positives before my missed period but I wasn’t tracking this month so no idea when I ovulated!!

Anyway, thoughts? This picture is unedited. Been doing the LH and that keeps getting darker and not lighter... usually lighter when close to period, and darker for pregnancy.
