Positive urin test negative blood work

Alexis

Positive urin test negative blood work been feeling nauseous first thing in morning and at night few days after ovulation I had what I believe was implantation bleeding lasted 3 day very very light was brown and only a little on panti liner and when I wiped I am 6 days late on my period i am having milky white discharge which I had with all of my past pregnancies. I had blood work and it said negative for pregnancy but I was getting positive urine test I’m gonna take another home test today but I’m so confused has this happened to anyone else and they ended up being pregnant ? I got blood work done in Monday which I was late for my period by 4 days
