positive pregmate, negative FRER?

three tests three days in a row, progression looks darker to me. but all 2 FRER have been negative! has this happened to anyone else? do y’all think this is my bfp and im pregnant or just faulty tests? i’m confused 🥺

UPDATE: Took 2 FRER this morning and completely NEGATIVE. i am so confused. could this possibly be a chemical, miscarriage or ectopic? my period on the 12th was a week and a half early and super painful and longer than usual. i’m wondering if the hcg was still in my system. i don’t know. someone HELP :(
