Pregnant or dumb apps?

Hey guys so I have to period tracking apps this one and another this one says I'm 5 days late but other says I'm suppose to start today my other one is usually spot on I don't have any signs of starting my period and I've test and it was negative but I know you can get a false negative.. The last time I had unprotected sexual was May 4th so if I am it wouldn't show up positive yet.. So I guess I just play the waiting game? And if I don't start test again..?
