Positive home test negative blood test

Adrienne • I`m 33 and trying for my second baby. I`m also incredibly impatient! We`ve had two chemical pregnancies in 6 months.
Just got a positive hpt this morning. Two cheap ones from the Internet had VFL. I went to get the blood test and it came back negative!!? What the heck? Yesterday my hpt were all negative. I'm 10 dpo. What is going on!!?
