I had the mirena (levonorgestrel) removed about a week and half ago. i haven't had any bleeding although, about six days ago i had one line of pink. is this normal?

Yes: The progestin in the Mirena (levonorgestrel) has been causing the uterine lining to stop growing and get mature. Once it is removed, it takes a little while for your estrogen to stimulate growth of the lining. Bleeding is the result of shedding that lining after your progesterone level drops each month. Your progestin level dropped when the Mirena (levonorgestrel) was removed but you had very little lining to shed. Hope this helps
