I just want to ask, I miss 1 pill in the 3rd row, exactly the 21 day taking of pills. my timings of taking pill is 9:30pm then I forgot to take. So I take 1 pill as soon as I remember and that is 1:30am. do I need to continue to take the remaining active pills also the 4 white pills.? what should I do? Still am I safe? Thank You.
