I don’t know what to think!?!??

So I had what I thought was a period May 1st for about 3 days but I have been feeling a really sleepy since yesterday (only symptom with my first pregnancy) so I tested today since I had a test at home already. But I can seriously see a faint line! But if is true it should probably be darker right?? Or has anyone had a hard time getting a positive?? When pregnant?? HELP
