"i&#039;m 26, just celebrated my 1 year anniversary with my mirena. i remember like if it was yesterday when i had it inserted. it was a very, very painful 30 seconds. my doctor said it would only be a pinch...ah definitely not just a pinch. it wasn&#039;t that my doctor did anything thing wrong, my doctor is the best, i just was not ready, or expected that kinda of pain. i luckily had taken two days off so i rested and i did have painful cramps. i was spotty for about a week after that.  cramps are pretty bad but it beats worrying about being pregnant. even though the insertion was painful, ladies i strongly recommend it to every woman who wants a reliable birth control."
