Levonorgestrel
"The mirena is amazing. I've had it in for almost 6 months now. I had some heavy bleeding in the beginning bc I never had a child before and my body naturally pushed the mirena out. I went back to my doctor and they put a new one in and this time its stayed in. After the second placement I had heavy bleeding for the first month. After that I had no bleeding at all. I haven't had my period in 3 and a half months. I do get light period every now and again but its never heavy enough to have to use a pad or tampon. All you need is a panty liner and you'll be good to go. If you have the mirena put in and start bleeding soon after make sure you don't use tampons bc this can likely pull the mirena out and that would hurt. Its amazing!"
