late period/pregnant?

Raegon

So my period is 4 days late. I took a pregnancy test yesterday, a clear blue brand. The one that is supposed to tell you like days before your period starts and it came back negative. I was a little bit discouraged because my husband and I would love a child. But I’m also confused, why is my period late? Could I still be pregnant and the test been wrong even though it was a high brand test? I am having no other symptoms. Someone give me some insight please.
