birth control
"So I cannot vouch for effectiveness since I just got it today but I wanted to share this. I have never had a child so I read the reviews below and was terrified about the pain people claim lasted 24 hours to a few days. I will admit the pain at insertion was so surprising I got lightheaded. About 20 minutes after insertion the cramping has subsided and I don't feel as awful as I thought I would. Mild cramping but that's about it."
