Good sense test compare to Clearblue

Has anyone used these are they accurate?? I tested with frer this morning and the line was so faint so I took another in the evening a cheapie one it says compare to clearblue early response? Anyways this showed up immediately! My period is 7 days late I’d be about barely 4 weeks. I wanna know how accurate this is. Should it be darker for a week late?? I did have what looked like implantion bleeding last week! And sex the week before that.
