"i decided to choose paragard because i haven&#039;t done well in the past on hormones. i tend to be very sensitive to hormones and feel sick, gain weight and become very emotional. i decided to try paraguard and so far have loved it. yes you have cramps and slightly longer periods, but you get your period almost to the hour every month. i have always had heavier/worse cramps than most people i know so this has been nothing for me (at least nothing some advil or a little wine can&#039;t fix!) it was a little painful being put in but its effective right away and lasts for 10 years!! i have had this for almost a full year now and will definitely be keeping it until i decide to have children."
