Advice on iud

Michelle
Hey ladies! I have been on the Paraguard IUD for almost two years now. A few months ago I took some weight loss supplements because I am a competitive power lifter and I have not had a period for 3 months. I was curious if this was related to the supps or if IUDs can mess with your periods. I have not had any interruptions before this and was just worried. Any advice will help. Thanks.
