birth control
"I cannot speak for the effectiveness of this birth control method, since I have had it for a very short time, however the insertion was nowhere near as painful as I expected. The doctor and nurse at the clinic I went to both warned that it would be very painful for a short time, but it was less than 30 seconds of sudden cramping, followed by a day of very dull cramping. I'd rate it as a 1 on the pain scale of 1-10. The doctor mentioned that if the insertion was relatively painless (it was for me), then the cramping experienced later, during the first days of a period, would also be very manageable as well."
