Advice- multiple BFP, negative blood

Shannon
I got a very faint BFP yesterday morning, and a slightly darker BFP yesterday afternoon. I went and got a blood test yesterday to confirm, this morning I took a hpt and it was either too faint to see or negative, blood result came back as negative, but I just took another hpt and it's the clearest BFP I've gotten, not faint at all. Any thoughts on this?
