What To Do If Missed Taking Primolut Tablets In The Curent Cycle?

Hello, my name is Fatima and i was given primolut by my gynocologist but i cannot get a hold of her right now. I was told to take it 15days after my cycle for a period of ten days but i have forgotten and have yet to take the pills. I am off by 4 days can I still take pills for the remain 6 days or should I do all. Sorry I was told to take 2 a day for 10 days. Please can you help me. Fatima from Portugal
