birth control
"No no no.  A piece of copper implanted into your body? I had it in for 1 month. In that time, I felt like I was always about to have a period, I never had cramps before. I experienced anxiety, racing thoughts, repetitive thoughts, empty feelings, extreme anger and resentment, extremely itchy labia and skin, tremoring vision, nausea, headaches, terrible back pain, sharp joint pains, ear aches, sadness, and the worst TOTAL LOSS OF SEX DRIVE. Also vaginal dryness. I basically couldn't feel myself on the inside. The stress of unplanned pregnancy is easier to deal with than this. Anything that causes this as it "settles in" is just messed up. Just because the side effects may go away doesn't make it OK. It's your body numbing out to this hideous device."
