Symptoms, but bfn

Ttc is no longer any fun. I'm tired of getting bfn on every test. This month I just feel like we did it, but the hpt always proves me wrong. I woke up today feeling awful. Cramping, dizziness, and nauseous and still got a bfn. I know it's too early, but I feel like if I have these signs then I should be able to get a bfp. I'm just venting from frustration.
