"i gave this a low rating as it has been the worst experience for me. i have my period 2-3 weeks out of every month and some months i have it the entire month. i get cramping for a week out of it. it is very effective as the &quot;birth&quot; control part of it. i&#039;ve had it for almost 3 years and am due to get it removed soon. i waited this long because i didn&#039;t want to have to pay to remove it and figure something else out. no birth control has been great for me. so disappointing."
