4 days of very faint BFP's no symptoms, am i pregnant?

i am now to this, but hope someone may be able to help. We are TTC and this month i did a pregnancy test 10DPO and it was very faintly positive, the next day i repeated the test and did a digital test all positive but very faint. I am now 14DPO, AF due tomorrow, BFP still very faint and temp still raised. Is it normal to have No pregnancy symptoms and such faint lines for 4 days?
