Feeling discouraged...

I took a test back on the 5th & got a faint line(as seen in first four pics). My bf wanted me to wait to see if AF would show up, which was suppose to happen today. She didn't show, so I bought a couple of tests. I know I should use fmu, but I went ahead & tested. Idk if my urine was too deluted or bc it was in the afternoon, but it doesn't look like there's anything there. Just feeling a little down bc I want this so bad!
