Hi Girls,I wanted to know who all use digital OPK with that smiley face thing.What time do you usually use and do you really dont pee 4 hrs prior to taking the test as the test says to do .And you you also not drink anything for 4 hrs before taking the test.
I am asking bcoz 4 hrs without peeing is a little difficult for me

.But i heard for OPK FMU is not very reliable as LH surge occurs later in the day and ideal time to test is betwwen 12 to 8pm or somthing.
this is the 1st time i m using this smiley face thing as i am fed up with lines and checking which one is darker.
