faint lines....

I did 4 home pregnancy tests and all came back with a faint line. Called my OB and got into the office the next day due to PCOS and unsure when my last period would have been. They did a urine test and also got a faint line, as well as had my blood drawn. They called today saying my hcg is only 1.1. I'm so confused. I thought I was for sure pregnant. Go for more blood work tomorrow and have another appointment with OB on Monday. We have been TTC since May. I am not on any meds that would give me a false positive.
