I'm on my way for a beta blood test (several hour round trip) which will obviously answer all my queries but in the meantime maybe you can help my obsessive overthinking!
Got a very faint BFP at 6dp5dt (FET) on FRER and another faint one the next day on clear blue early, neither FMU. Yesterday at 8dp5dt I got an even fainter BFP on FRER using FMU. Tested again later that day with clear blue and it was about the same faintness as the previous clear blue.
Last night I compared the clear blues and the bottom one is the more recent. Obviously they've dried out a fair bit so maybe that explains why the more recent one now looks stronger? It didn't look stronger after the first 3 mins.
I'm assuming chemical I guess. Any views?
