18 dpo, AF 4 days late, In need of encouragement...

I need some encouragement from anyone who has had late BFPs, or faint BFPs that eventually became a clear positive. I have been testing, testing, and testing some more because I have gotten super faint lines for 4 days. I swear I see it, and then I think maybe I don't. Here are some that I have taken...can you ladies add pictures of your questionable tests that eventually became a positive? I have all the symptoms, but coming up short and the anxiety is really getting to me 😩
