Hi Tonydayl,
do you know how long your luteal phase usually is? I haven't had much experience with post-O temps as yet but I have seen that people with all kinds of charts can sometimes end up with a BFP. If you're a few days past your luteal phase length, you could be in with a very good chance!

I've never had an evap line on a test so I'm not sure how they might differ from a positive result.

I'm thinking vibes for you tomorrow morning !!!!!
