Does anyone know?


Does anyone know what the 2 strips inside the clear blue digital advance weeks estimator actually test? And I know you're not suppose to take them apart but I always do lol call me crazy. I know the lines don't mean positive. I'm just wondering what they do mean? 10dpo fmu I got bfn soo I'm just wondering. I tried to Google but couldn't find a straight answer about the 2 test strips ?

1st pic is the result 2nd pic is time you take it apart and 3rd pic is if I flip over the 2 test strip
