Cb digital HELP!

kirsty

I had a miscarriage back in October at 8wks. I have recently found out I am pregnant again, clear blue digital said 1-2 weeks on 23/02/19 just taken another one today 4/03/19 and it still says 1-2 weeks 😭 how accurate are these? I'm petrified that my HCG is not rising again 😭
