I'm getting pregnancy symptoms with the mirena, (levonorgestrel) i know i'm not pregnant as test came out negative, is this normal? need to put mind at ease..

Normal: Mirena (levonorgestrel) has progesterone as its active ingredient. Most of it acts locally but a small amount is absorbed. In sensitive women, this can cause pregnancy-like symptoms. Progesterone was named because levels rise during pregnancy and this helps support the pregnancy. Progesterone is one reason pregnant women feel the way they do. Best wishes!
