Test line isn't getting darker

[Dan6158]

I've tested 3rd August, 6th and today and the lines aren't getting any darker. The clear blue indicator has stayed on 1-2 weeks too, should I be worried??

Have you made an appointment with the doctor?
I would inform the GP. Some tests are a lot more sensitive then others. Clearblue would require a higher Hcg level I believe. xx

If lines aren't getting darker on FRER I'd be concerned. If it's other tests I wouldn't, esp if they are internet cheapies. The clear blue digitalis are a bit less sensitive so may take a while to change, when I had my missed miscarriage they didn't progress beyond 2-3 weeks so it did indicate a problem, although I didn't realise.
