those of you have used norethisterone or the pill to delay a period..

my af is due tomorrow and I am taking dh away for a night for his birthday. I started taking norethisterone (medication to delay af) on boxing day (3 days before af was due) and today I feel like af is on the way, feeling wet and keep checking. Does anyone know if a it could just be an increase in cervical mucus or is af still going to come?

If you have used the pill to skip a period do you still feel like its coming when its due
