"i have had the copper iud for close to two weeks. unprotected sex with my boyfriend and long term birth control are the only pros. cons include: acne, anxiety, low sex drive, fatigue, weight gain (4 pounds in one week). cramps, random shooting pains. i am a thin woman with a high metabolism &amp; have found it impossible to lose the weight. i look puffy &amp; feel horrible. i wouldn&#039;t wish this experience on anyone. i&#039;m getting it removed today."
