Confused! 8-9dpo

Nikki

So yesterday around noon, I got a faint bfp on 8dpo. I know early but I couldn’t help myself. Then another faint bfp later that night. 9dpo fmu and got an even fainter positive. Then later in the day I got a bfn. I’ve had a chemical pregnancy before and this doesn’t feel like that. My symptoms are intense. Could it be a faulty test or am I just testing early still?

Oh and I used the first response test.
