4 faint positives...i highly doubt its wrong.....as i have read there are only evaps and wrong negatives....but if they (lines) have color irl and they appeared before the timeline then i strongly believe that this means a bump for you

I had veeery faint positives and some days i didnt get any...and the lines kept on disappearing...but...i still got my bfp that month.....the symptoms also are super promising...i would say that run away from your bf and test again ..or..just wait

good luck
