i had the mirena coil fitted in january this year and it was painful having it put in and ever since iv had it put in iv been getting terrible pain in the lower part of my stomach on the left handside.it can come on with no apparent reason sum times after sex and wen i exercise.i also found myself getting head aches, spots and really sore and chapped skin on my face.im a moody person when im having a period but find myself more immotional since having this put in.my periods have lightened but seem to be for a longer juration then they were before.i have to go for a scan to find out whether iv got cysts on my ovaries and if they are large then i have to have them removed.im only 24 and have a 2 year old boy already but was hoping i could have children later on but sounds alittle daunting with the cyst senario.just think before having it put in.it has done what it was upposed to do as i havent fell pregnant but the side effects aint that good
