Hello doctor, Hi, i never used any birth controls before. i gave birth to my only son 2 years ago, normal. 3 days before my obygn suggested mirena and also placed it. i had slight bleeding on first day. after that i am noticing thick white discharge with very light brown or red blood. it leaves smelly odor. during pregnancy i had vaginal infection, but never had this kind of odor. i am negative in std. haven't had sex for past 1 month my obygn said not to worry abt this. but i need an second opinion. is this normal?! will it go away?!
