Thanks everyone. I took another test last night with the results in text pregnant/not pregnant, and got a BFN. However, tonight I took another below and I swear the line looks darker. It really discouraged me getting the BFN last night, but AF isn't here yet..
They are definitely positive, I'd say it's just too early to get a positive digital test. Wait a few days and try another digital. I'm sure you'll see 'pregnant' then!
