pregnancy test getting lighter?

Alexandria • Wife 7/3/11💍 Mommy to Mila 2/20/19 👧🏻 + Eleanor 11/23/21 👶🏻
I got my bfp on Tuesday but had some
Light bleeding. Called the doctor and he told me to keep taking test and make an appt on Monday. Took a digital last night that was positive but took 2 frer test today and they are both really faint! Is this a possible miscarriage?
