birth control
"I'm 20 and have had the Paragard IUD for almost 4 months. The first couple days after insertion were the worst. Although the procedure itself was quick and somewhat painless, bleeding and cramps were a serious issue over the following weeks. The cramps were painful to the point where it was debilitating but taking painkillers helped a lot. Between spotting and periods I was bleeding almost nonstop first few weeks. The IUD made my periods longer and heavier (went from 5 to 8 days) and I became extremely susceptible to bacterial vaginosis, which has recurred  continuously (and isvery costly to treat). Side effects (BV and bleeding) made me unable to have unprotected sex, which ruined the point of the birth control. Things do improve with time"
