Birth Control
"I had to stop the combined pill (Yasmin) after 3 years as I had started getting migraines. 
I am lucky my mother works at a family planning clinic so if I have any questions I just ask her. I chose the Mirena coil as the copper coil has a high chance of heavy periods and cramp (which I already suffered from).
My periods seemed to last slight longer, but after around six months they have get become very very light. During the 6 months I had bad cramps when due on my period which last days, but now have really settled.
My acne came back from pre-combined pill, but I manage this with antibiotics
I have had no weight gain, but I do have a healthy lifestyle.
Everyone is different, but I am glad that I perservered with the mirena."
