Positive Hpt concerns

Dani

Hi, I've been testing since early and had plenty of negatives. Had my first positive with Clearblue around 12DPO the rest are up until today, 20DPO, mostly all with FRER, apart from the Clearblue digital.

Should I be concerned that the line is still faint? I know people say line progression isn't always a thing, I only tested again today for re-assurance that I am still pregnant due to a miscarriage last year.

Thankyou x
