Hello girls so this is my first month with cb advanced, I've been doing it along with cheapies opk, so in the morning I've been having about nothing on the cheapie and flashing smiley on the cb for 5 days, I checked with the cheapie in he evening yesterday and looked almost positive and this morning atill flashing on cb and no line on the cheapie, the instructions on cb say not to test other than with fmu, should I just try it on the vending? This is cd23
