birth control
"Since June 2017! I was scared after reading these painful insertion stories, but the actual insertion didn't end up hurting. Took two Motrin 40 min before and it was just a slight pressure for ~2 min. I had some spotting that day and mild cramping, but felt fine. I started spotting about a week after insertion; for a few months I spotted for a week every other week. By September, I was back to regular light periods. I've had no side effects besides feeling slightly emotional around my period. 
My biggest comment is to remember that everyone will have a different insertion experience depending on pain tolerance, OBGYN, and your individual body. Talk to an OBGYN you trust and follow up if you're having excess pain or side effects. :)"
