Glow messed up

Nicki • Going to be 21 years old soon and ready for baby #1
Glow had everything all messed up I'm actually 12dpo today and shouldn't start AF for 2-3 more days. Yesterday it was saying I should start the 31st one Sunday??? Does it do this to anyone else?? Its so frustrating... Still no sign of AF at all. But all negative hpt tests ):
