How long did it take to get a positive???

Good morning, ladies! So my period was due Friday and it is very regular. Like clockwork honestly. I took a test on Friday it got s very faint line, and the same thing happened this morning. The lines are so faint that they won't even show up on camera. So my question is, how long did it take for you to get a definite line after your missed period? I feel a little discouraged. All comments would help. 
Have an awesome sunday! ☺️
