"chose the mirena after heavy menstrual bleeding from paragard. i loved my paragard and mainly had it removed because it was ten years old. a couple days after insertion of mirena panic attacks began, also dizziness, nausea, loss of appetite. i had sharp, stabbing pains in my pelvic/abdomen, head, and chest. upon removal symptoms resolved. insertion was easy with cervical softening meds. mild cramping and some spotting after. wish it hadn&#039;t made me feel so sick!"
