Help me please!

So I had a feeling I was pregnant for weeks now! My period was late, and I kept getting negatives. Up until 9/10 days late! I got a bfp on first response, a faint positive on a dollar tree test, and a Yes+ on a digital.

I have an appointment today but I’m so worried that because I got a BFP so late that something will be wrong.

Has anyone gone through this?
