Line progresion/should I be worried?

These two tests are only 1 day apart. Both were taken at 1:00pm. I had not had anything to drink or much liquid In my breakfast to "dilute" the results. I actually had the same exact thing for breakfast for both days. These are equate brand early pregnancy tests. I know blue dye has a bad rep. They're just the only kind I have available to me right now. The bottom is the latest one. For the sake of line progression.. Should I be worried? I am estimated to be around 14 DPO. Hope I didn't leave anything out... Thank you in advance!

UPDATE*** the reason I do not use FMU is because for whatever reason the results do not come out as dark. Not sure if this is bad. But if found I get the darkest results around noon. Hope that helps clarify that
