We are ttc no.2 and I went for a day 21 blood test about 10 days ago. As well as AF turning up on Weds, I was also told by my GP surgery that the lab had cocked up the processing of my blood test- they separated the blood incorrectly or something! I was SO angry about it . I have 35+ day cycles so thats a long wait til next time. Also, I am probably going to be on holiday on 7dpo (in the UK) so I won't be able to get to my local hospital. Does anyone know if I could get a blood test done at a different hospital, nowhere near where I live?!
