So yesterday I got positive pregnancy test and so I went and got blood work done yesterday as well but my blood test showed that my level is only 1 and so all day today I have been testing and getting postive i even got a first response digtal and it said yes. So my question is have you ever had a positive urine test but a negative blood test and still had a viable pregnancy.

P.s. I get my hcg retested tomorrow.
