11 DPO too early? BFN turn into BFP?

Kayleigh

Did you get a BFN then tested again a few days later and got BFP?

I got implantation bleeding 8-9 DPO (it was spotting-light flow for 2 days which is why I doubt AF came early even tho I'm irregular). IB ended this morning. I jumped the gun, got too impatient and tested (was not fmu).

It was BFN. My body feels off and have the symptoms. Did I test too early? What was your experience?
