Eve can't count? 😫 please help

Question

Okay so I take the pill for 21 days and I have a 7 days break when I get my period. So that means my cycle is 28 days. 
Yet eve constantly calculates my periods 2 weeks later than they're supposed to come. What can I do? Is something wrong with the app?

Answer

Do you have it set as 28 days for your cycle? And that you're on the pill? When I first started it took a couple months for it to get it right on time.

Answer

I also have this issue except I don't use the pill I have the nexplanon implant and my period is weekly. I've put in all the info I'm correctly except for the average cycle length, before bc it was like 25 but now it's a much smaller number, but the lowest number they have is 22 which doesn't match me at all so my prediction calendar is always way off
