I’ve been testing with easy@home strips since 11dpo and now af is late and nothing so far , the past two times I tested I thought I see something but it was so faint it could have been an indent so I’m wondering if these tests are sensitive enough in my case has anyone got negative on strips then went out and bought an FRER and it was positive. I’ve been debating on going and getting a FRER let me know what y’all think
