"Honestly, if you want to experience PAIN then this is right for you. Yeah it prevents pregnancy and what not but the amount of pain you experience in your uterus is totally not worth it! I am 20 years old and I've never experienced this amount/type of pain. Its extremely harsh and it feels like needles piercing through you! I gained 4 pounds the first week and I'm VEGAN! My breasts got bigger too and I'm not complaining but the pain just isn't for me."
