I'm 45 and over the last few years my periods have got more frequent and much heavier. 2 days of needing to wear the thickest pad and having to change it every hour at least. My ferritin is around 10, rises to 20 after 3 months of iron tablets but drops back again once they are stopped. The GP has recommended I have a mirena coil. The reason I'm hesitant is that I suffer from hormone headaches and migraines. I tend to get them the day after ovulation and then again the couple of days before my period. Over the last couple of years I've been getting more frequent migraines with aura which I guess is linked to perimenopause and fluctuating hormones. I have read that the mirena can actually make migraines and headaches worse. I asked the GP and she just said that's true for some women but some find they get better. So, could I ask if you have a mirena whether it has made any difference to you headaches?
