Hello I had the merina in for 8 months and it was the worst experience I’ve ever had. I bled for the full 8 months in and out of the hospital, losing golf ball blood clots and I always had a dizzy head. I have gained 25 pounds in weight and my breast and always sore to the point I cant take my bra off. I have anxiety and panic attacks so bad they keep from leaving the house most days and I get heart palpitations now after having the iud. I have had to have both tubes remove and a cyst on my ovary plus a dnc to get rid of the tissue in my uterus. My life has changed and not for the better with having the iud put in.
