When would I consider my period late?

I have two different apps that show my af tracking. One says that I should start on the 12th, while the other says not till the 14th? Not having any af signs right now and I usally get them a day or two before. My cycle is usally about 28-30 days

So would I just need to wait to call my period late till after the 14th??

Any help is appreciated!
