"so i&#039;ve just had my iud for about 2 weeks now. the cramping is no exaggeration. it is very painful and does feel as if it was a contraction coming on. my period has lasted now for about 12 days and doesn&#039;t seem to be subsiding. i will give this a try for 3 months and if theres no improvement will need to change to a different method. i have a 22 yr old and a 14yr old and the only good thing about the paragard is the fact that i don&#039;t have to worry for 10 yrs."
