Levonorgestrel
birth control
"The insertion experience was probably the most painful thing I have ever had to go through, and I'm not going to lie about it.  I'm an 18 year old who has never had a child, been pregnant or any of the above so my cervix has never been messed with until this moment, which made the procedure ever worse.  But, now that it's been about 6 months I can say it was completely worth the experience."
