Shouldn’t it be darker?

Victoria

Tested Wednesday night, had a line that showed up out of the time frame so tested again yesterday morning with fmu. Had the faintest or faint lines show up within the 10 minute time frame. Just tested with today’s fmu and got this... it showed up after at around 4 minutes but it’s not got any darker. I know it’s there but shouldn’t it be darker than yesterday? Need reassurance guys 🙏🏻 x *EDIT* not even due af until Monday 😲
