I got my Mirena in Sept. 2007, and 4 the 1st 3 months, there was disharge..liquidy, white. Thhe bleeding was sorta brown, and went on 4 a month or so, i suppose it was the thinning of my uterus? IDK...but, here it is, Apr. 2008, everything has been fine up until right now, I am haveing thick, yellowish disharge, w/ no harsh oder, i have been checked 4 all STD's so, it is not that. Not sure if i shhud get Monistat or what...b/c I am unsure if it is a yeast infection, or just a phase of the mirena insertion! somebody please help! I need some input from others, if u have experienced the same, or similar effects.
