birth control
"I have had mirena for 6 months, insertion was not painful just a slight pinch feeling, had a continuous period with severe cramps for 3 weeks after with worse cramps than ever before. I have had weight gain, spotting and bleeding for weeks at a time, headaches, severe lower back pain and cramps that feel like contractions for the last 4 months or so. The side effects have gotten better, still with bad cramps and weight gain, have not had a period in about 2 months. It is convenient and easy if your a forgetter like me, and if given enough time to adjust it is a good thing."
