"i was nervous to get mirena after reading reviews, but my doc strongly encouraged for medical reasons. about 3.5 months ago i got the iud inserted. while i survived, i&#039;m still haunted by how painful it was. there was a slight complication (apparently my uterus was tilted so the 1st attempt at insertion failed &amp; she had to give me a numbing shot in the vag &amp; adjust my uterus) the 2nd attempt succeeded but the cramps were so intense. cramps lasted 2 days &amp; i bled for 2 weeks straight. after that my period came normal but lasted a couple days extra. my last period was slightly lighter than usual so i&#039;m hoping it drops off soon. so far it&#039;s been worth the pain bc periods are more bearable, it&#039;s super effective &amp; nice to not worry about a pill"
