faint positive on fr but no on dig

Ta

top is 10dpo, bottom is 11 dpo. yesterday on 11 dpo I took a fr digital and it said no. I thought I'd skip today because seeing that no was such a let down after I've got my hopes up:-( I know everyone says digitals need more hcg but when do you guys think I should take a digital? I have 1 left. today is 12 dpo
