Levonorgestrel
"I'm 30 and have had no children. The IUD placement was sooo painful that my body went into shock but the pain lasted about 10 minutes and that was that. I've had my IUD for a month and a half now and so far I love it!! I've had no side effects at all. I stopped spotting after 2 weeks and haven't had any limitations intimately or fitness-wise! (Boyfriend can't feel it either) No more pills for me! I'm so happy I did this for myself!"
