I’ve had the mirena in for almost 2 years and it’s been working great as a contraception and minimal side effects (very light periods).

My first year of the coil seemed to be okay. Took a while to get used to and on the grand scheme of things after about 3 months my period pretty much left.. but in the last year, I’ve been getting symptoms of anger, forgetfulness and generally feeling checked out. Going to speak to GP to find another option.
