It just shows the tests have worked ,you will get line in the test no matter if it's postive or negative,you might not of had enough HCG for the second test to pick up ... sometimes you very rarely get false positives...I'd suggest getting a blood test x You could of had a chemical pregnancy...x
Going to try a different test later to be sure. I had vfl progress to fl on strip tests earlier this week, and then confirmed with positive digital test 2 days ago. Definitely must be a chemical if it’s negative later.
Have you tried a different test?
