"i had the iud inserted on april 19th, and about a week later i started experiencing a chronic headache. it literally lasted 24/7. i was also passing large amounts of tissue, and experienced heavy cramping until i decided to get the iud removed at the end of may. i had massive bleeding for a week afterwards, but my headaches have not improved. i&#039;ve seen multiple doctors for this, and they think it was caused from the iud. i hope to find relief soon because living with this kind of pain is really depressing."
