I have had my Mirena put in a year ago after i had my second son. Since getting it i have had my period for 12 days and it seems to come twice a month. before i would only get it for 3-5 days!!! Im very emotional very sensitive at times and then times i have so much rage and anger it scares me. I get dizzy and have less energy. i have a huge appetite and i am still hungry after eating a huge meal. I know that all of this is because of the mirena an i need to have it removed. I honestly thought this was going to be the best thing for me and it has turned out to be the worst!! I am looking forward to having it removed soon!!
