"iud is good at preventing pregnancy.

the side effects of this iud has been awful. i have been on it for 4 months. i am 110lbs, 5&#039;4&#039;&#039;, healthy and i used to have heavy periods that last about a week. first month, i was bleeding heavily for more than 2 weeks, i also had brown discharge. i had cramps that occurred randomly throughout the month that was comparable to getting my iud inserted, but it was very short whereas before getting this iud, during the first 2-3 days of period i would have constant dull pain. bleeding calmed down after, and now at 4 months, my period lasts more than a week. i get light spotting for 3-4 days, then bleeding for 4-5 then brown discharge for several days. still have bad cramps and am emotional."
