I hate this and wish it was tomorrow morning already

This is so confusing and I’ll test again tomorrow, but am I seeing things? I took the one this am with fmu and ppl responded here that it was positive. I waited 4 hrs and retested and it looks like there is a line on the blue due but then the digital says not pregnant. I am on cycle day 30, first cycle of letrozole. Usually my cycle is 35 days but I did get a positive opk on cd 18. Do digitalis just not read this early? I also took it apart and do see a faint line on the digital strip…. Thoughts?
