is it a very faint positive?

Good morning ladies ! :) so I am not supposed to get my period for another week however I have been feeling off lately, unexplainable fatigue that I don’t usually get, cramps, I’m peeing more often as well. If I did my math right I’d be a little over 3 weeks pregnant so I’ve been testing about every 2-3 days. The top one was a few days ago and the bottom this morning. I’m not sure if it’s just me but I swear I can see that other like so so so faintly. These test are early detection up to 5 days so I will be waiting until my period is closer to see if it gets darker or not. What do you guys think; is there a line? Or any suggestions for more accurate results or brands?
