You guessed it more POAS stuff....lol
I did a little expirament with the save on test PG and OPK test along with the clear blue HPT.
The OPK test came up with 2 line in less the 1 minute as did the CBE but the save on test pg did not show 2 lines for almost 3minutes.
here is a pic after the 3min mark ------->
the two top ones are the save on test the bottom is the CBE
