Background
I'm 26 with two DD's and started periods at 8 years old 

Basically I've never felt I've ever been in control of them, never tracked them always a surprise to me when I do come on as I've always been on various different contraception except from TTC.
Well this time around I've opted for the copper coil had it a year now, love it. It's been the best one for me so far as I've always reacted badly to hormone type ones only side effect I've had is heavy bleeding, very heavy bleeding actually.
I go on holiday 4 weeks today and I've had a slight bleed today 
so I'm assuming I'll be on really heavy whilst on holiday, so would the GP be able to prescribe a course of the pill to stop it? Will it work or is it not enough time?
I've never had that type of pill before as I've suffered with migraines for most of my life so they won't usually give me these.
I can't have a good holiday whilst bleeding it's that bad for a couple of day I'm (sorry tmi) soaking through a heavy tampon in 20 mins.
Any help please? Totally clueless female failing at the menstrual cycle
