"i got it inserted in august  2014 and i know it was supposed to cause an irregular period. the first period i had was 4 weeks, then 3 then 2...i am on it currently (february 17 2015) and i&#039;ve been on it since december 28 2014. i am having extreme migranes, nausea, cramps, mood swings and dizziness. hopefully these symptoms will clear out and i will stop my period soon and have a regular one, or else i&#039;m getting it taken out. it works because i&#039;m not pregnant; but how am i supposed to have sex when i&#039;m always on my period? i&#039;ve also gained 15 pounds and i don&#039;t think its worth all the side effects"
