LH tests keeping getting faint despite not having reached peak

Victoria

Still having O symptoms. Breasts just got bigger the other day, sense of smell, etc. been doing the SMEP and BD’d last night in case I missed my peak. One app says 2dpo another app says O today. I’m getting really upset because my LH tests are being like this. I should’ve retested CD18 again that evening. I’m sure it would’ve been a peak.
