I'm due to be on my period when I next go on holiday. I currently have a copper coil and my periods are heavy for around 4-5 days then not too bad for the remainder. Average period is 14 (yes 14!) days. I will be bleeding for the whole week that I am away. In the south of Spain. Mid August 
I know loads of people take norethisterone to delay their period but I have a history of migraine with aura so I'm not supposed to take any hormones.
Are there any alternatives to delay my period or do you think my GP might let me take it for 1 week?
