Freaking out

d

Flow was due on Friday. I’m officially 4-5 days late (according to two apps) I’m on cycle day 34 which never happen. I took 2 pregnancy test on Friday and Saturday one was with blue dye which had a very faint line almost impossible to see and the other was negative. Maybe it was too soon to test?? When should I test again. Today I’m supposed to be finished with my period but it never started. I’m scared I’m gonna wake up to blood. I have no symptoms besides being alil nauseous but idk if that’s all in my head . I need answers ladies !
