"i had the paragard iud in for 8 yrs. when they first inserted it it hurt so bad and had experienced pain in my lower abdomen for days. i bled heavy for a week and spotted here and there during 2 month stretch. i also menstruated every 2-3 weeks during 2 months also. it got better and my body adjusted. my periods lasted up to 8 days each time for 8years. this past feb, i had it removed and had the tubal ligation. now my periods last 5 days. i believe the iud blocked my menstruation and caused it to come slowly and that&#039;s why it lasted longer.  iud was great for me because i didn&#039;t have to think about missing a pill, and other conceptions such as mirena, nuva ring, depo shot, and pills are way to hormonal and can cause problems...."
