Am I actually Pregnant?

Hey guys so I am 13 DPO, I would have possibly conceived around feb 2-7. My nipples look darker, my boobs look fuller, I have to pee frequently, and bloated, but no nausea, no morning sickness, no positive pregnancy test. I am 6 days late on one cycle app, 5 days late on another, and supposed to start my period on two other apps today and tomorrow. I have had slight almost unnoticeable cramps this past week and finally seen slight brown discharge today when wiping. I FEEL it that I’m pregnant but the test is saying otherwise. Am I just too early to test? Or I’m playing a trick on myself. I was thinking about waiting another week until after the other two apps predictive cycles to test again.

Update: calculated cycle wrong lol. Too early to test.
