anyone have the copper iud? have you had weird periods/cramping/nausea? how has it been for you? i had mine for about a year and half with no problems then all of the sudden my period was coming every other week. it still comes that way most of the time, but sometimes itll be like a month and a half. simce my period started coming so strange, I've had cramps and nausea at night. literally if its past like 10 pm I'm hugging my heating pad until my alarm clock goes off. I've been to the OBGYN and she thinks the cramping endometriosis and doesn't think my iud is hurting amything at all.
