birth control
"I got it inserted 2/11/14. Pain was terrible, felt hot and light headed like I was going to pass out after insertion. This lasted about 30 minutes then steady cramping for 24-48 hours after. I had spotting the first few months then it finally dwindled down to no spotting or periods at all. 

Other than the pain I'm happy with it. I'm having it removed next week and a new one reinserted after. I was told removal isn't as bad as insertion so I just plan on taking a day off or two after reinsertion."
