1 BFP and 5 Vvfl

I posted yesterday where i got a BFP on clearblue digital with weeks 1-2. Right after i tested 3 different test all came back vvvfl. Today i checked with another different brand and still i get vvvfl.

Anyone has experience with this type of test? Does the faint line still means i could be pregnant? Shouldnt the line be so much darker? I will visit doctors next week i just need a peace of mind. Thanks

Update: its been 3 days since i got my BFP on the digital test. I am 20 dpo and 10 days late period today. I took a test using fmu so i expect to have a darker line/BFP but still got a vvfl. Is my hcG that low that even fmu cant pick up high levels? Doctors visit in 2 days.
