Copper
"I got my paragard Monday March 20, 2017. Insertion hurt but it wasn't life alteringly horrible. Mild cramping that day, but I went home and could still live life just fine (I did laundry and made dinner). The next day I went to work and just took one ibuprofen to alleviate my super mild cramps. By Wednesday I was sprinting on the treadmill, spotting completely gone. Had intercourse Thursday, no string felt by husband, no cramps nothing.  I will review again after my cycle, but I have never been one to have an awful period. I'm a 29 year old 5 foot 105 lb female, I had previously been on the pill for 12 years."
