"i highly do not recommend this method of birth control. yes it is effective but in my opinion the side effects greatly outweigh the benefits. i had the insert placed november of 2013 and plan to get it removed as soon as possible. i have had extremely irregular periods and when i do happen to have one it lasts for 3 weeks. i have also developed ovarian cysts for the first time in my life. i gained 30 pounds in 3 months which is significant weight gain for me at the age of 21 years old. also i developed pregnancy symptoms such as weird cravings and loss of appetite. i do not recommend this and do not think it is a good form of birth control considering the side effects."
