Can a blood test be wrong?

Question

Hi all. I had a hcg blood test at 10dpo and it came back negative. Today I'm 13dpo and I've noticed my cervix is soft, closed but medium-high? Could the blood test be wrong? I'm due my af tomorrow but don't feel signs of it coming?

Answer

Could be too early. I had a blood test on a Wednesday negative, took a home test that Friday negative,  took another home test that Sunday and it was positive. Baby dust!

Answer

Yeah I did think that. As I know it shows earlier than a hpt but thought I'd see if anyone may of had this happen. Thank you for your responses 😊

Answer

Blood test is the most accurate form there is.

Answer

Extremely unlikely.
