I know blue dye tests are notorious apparently for false positives...and im 10 dpo today but I don't THINK I'm seeing anything yet..We haven't been trying long, I just see a lot of negative things about blue dye tests. Never took one though my self. Thinking of just getting a blood test at a labcorp for 50$ in a few days just to settle this sooner rather than later. Home preg tests maybe pick up levels of 25 or higher...my sister found out with a blood test and her level was only 13 and she is 5 months prego now
