Don’t want to get my hopes up

So I honestly don’t know if I’m 10dpo or 8dpo. I know I ovulated around Monday-Thursday of last week but not 100% sure when. I took a FRER a few days ago and saw a very super faint line but it wasn’t enough to convince me. We are trying after a miscarriage in December so I don’t want to get my hopes up...I want to be pregnant more than anything right now. So I took this wondfo this morning and I swear I saw the faintest of lines (I know wondfos don’t pick up as soon as FRER so a faint line a few days after a FrER faint line would make sense I think). The camera wouldn’t pick up the line, so I went back and looked an hour or so later and was able to see it without squinting. I know you’re not supposed to look after 10 minutes of taking the test, but I did see a line within 30 seconds of taking the test. It’s just darker now. Is that a thing? I have been taking wondfos all week and non of them have an evap line, but I know that doesn’t mean this one can’t.

Has anyone else seen a line right away but it was easier to see an hour later?
