Can I Take Norethisterone To Delay My Period While Using The Mirena Coil?

I had the Mirena coil fitted 1.5 years ago for heavy periods. Although it has reduced the heaviness of my flow it hasn’t stopped my periods completely. I am due to go on holiday and also due a period. Am I able to take norethiestrone 5mg 3x a day to delay period if I have a hormonal coil already?
