I had my Merida IUD put in last month and have had cramps and bloating from day 1, 18 days later i'm spotting and bloated and moody i have had headaches. I stopped taking the pill because of the migraine headaches but at least if i got a headacke it would just be around the time of my cycle and than things returned to normal. Since the Merida i have not felt myself at all, i have no energy and feel like i'm gaining weight. I am calling my doctor to discuss having it removed. I'm glad to hear that i am not the only one going through this i thought it was just me. My doctor said that i have the rolls royce of IUD's and they have not had any complaints. Maybe she should vist this site.
