Need help/suggestions

4 days late. Took these tests tonight(Thursday), which are the first tests I’ve taken since Sunday(expected AF). Faint lines on Walmart tests but don’t see anything on the FRER. And I just don’t trust the Walmart tests so I guess having a negative FRER adds to that. Going to test tomorrow with FMU but just want to hear any advice or suggestions. If I’m not pregnant I just want AF to come on so I can try again.😒
