When should I take my first Cerazette tablet if I have stopped taking Orgametril?

I took from the 5th day to the 25th day of the orgametril cycle because it was a cyst, which in the meantime pekla but the doctor told me to choose the packaging for the end. Now I am in the 4th day beige orgametril and I look forward to the period however yesterday there was brown sleading and today mucus with blood but only in the toilet, on the sanitary pad does not. 1 day of the cycle I have to take cerazette. Do I have to wait until tomorrow and the tailoring will be on the sanitary pad Do take the tablet already today when there is only blood with mucus in the toilet. Please help
