"i had paraguard put in - super painful but that&#039;s a given. after 3 months i went in to have the strings checked like i was advised, no problem there. 3 months after that (so 6 months after insertion) i went in for my annual gyno check up, during the routine preventative ultrasound i found out i was 1 week pregnant. i asked if i had done anything wrong, how could it have failed?! and she just shrugged and said it was 99.4% effective and i just won the lottery. she removed the iud and advised me on the complications and asked me to rest, think and come back in one week. i did not stop bleeding the entire week. i ended up (spontaneously) aborting - which caused me serious psychological trauma and created barriers in my catholic family and community."
