Feel like throwing in the towel

I'm an impatient woman by nature and have been testing NON STOP since like 6ish dpo (not even really sure when I o'd) and I think my eyes are ALWAYS playing tricks on me. First I thought I saw a VVVfp on Tuesday, but have been testing BPNs until at 330 this morning when I got a POSSIBLE vvvvfp but ran to target just now and used very concentrated urine and nothing. 😢 FRER says that at 4 days before your missed period it's 96% accurate. I'm just emotionally and physically drained. I'm done. So heartbroken😭
