"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 "birth" control part of it. I've had it for almost 3 years and am due to get it removed soon. I waited this long because I didn't want to have to pay to remove it and figure something else out. No birth control has been great for me. So disappointing."
