Period 2 days late...

Amber • Mommy to 1 beautiful baby girl 💕 pregnant with baby #2 ❤️

Been testing since 8 DPO and my period is 2 days late, normally ALWAYS comes on the 12th. Is there a reason I’m not getting a + test?? I see so many women getting pregnant by 13 DPO. Anyone else in the same boat?!
