BFP with negative bt

I'm confused. Sunday morning I got a faint bfp with fmu. That night through this morning I got a bfn. I had blood drawn Monday afternoon, it was negative. The bfp was clear as day. I'm 9/10dpo?

I had my hopes up and now bam. I ovulated early this cycle and my period is due the 18th.

Idk what to think.

It might have been a chemical pregnancy... sorry!

The faint BFP could have been the antibody strip. Because nothing is more reliable than a blood test. I'm sorry.
