Brown discharge during Mirena

Mirena is one of modern safe contraception – it is a special type of IUD (intrauterine device) which is soft and flexible IUD that releases small amounts of hormone locally into the uterus. Mirena (levonorgestrel-releasing intrauterine system) is a hormone-releasing IUD placed in the uterus. Mirena also treats heavy periods in women who choose intrauterine contraception.
In most cases Mirena insure safe contraception that lasts up to 5 years.

It is important to know that:

red check mark very small  Mirena is more than 99% effective at preventing pregnancy;

red check mark very small  Mirena can cause vaginal infections and pelvic infection (PID) which could provoke unpleasant brown discharge between periods;

red check mark very small  Mirena is also proven to reduce heavy periods in women who choose intrauterine contraception but could provoke brown discharge in women with heavy periods in history.

Mirena IUD

Brown discharge is one of unpleasant side effects of Mirena. During first 6 months with Mirena you could experience the brown discharge.

Main causes for brown discharge during Mirena use are hormonal disturbances and/or infections (vaginal infections and/or pelvic infections). In both cases the endometrium (internal uterine lining) is damaged.

The percentage of women who develop brown discharge because of PID while using Mirena is about 1-3%. The risk is highest shortly after placement (especially within the first 20 days) and if you have a vaginal infection at the time of placement. After the first 20 days, the risk of PID is reduced.

During the first three to six months of Mirena use, the number of brown discharge/bleeding and/or brown spotting days may be increased and bleeding patterns may be irregular. Thereafter the number of brown discharge and/or brown spotting days usually decreases but brown discharge may remain irregular.

Brown discharge could appear after Mirena insertion – it is pretty common and many women could experience brown discharge during one week after Mirena insertion. However non stopping brown discharge could be a sign of vaginal or pelvic infections and a health care professional should be contacted immediately.

Recommendations for women who suffer brown discharge after Mirena insertion:

red check mark very small  Mirena IUD is a foreign object that is introduced into the body and brown discharge or bleeding are common for the first few weeks after insertion. Wear a panty liner or a light maxi pad – use unscented panty liners or pads;

red check mark very small  If the brown discharge has a strong odor, it could be a sign of an infection other than Pelvic Inflammatory Disease. Visit your doctor immediately;

red check mark very small  Take care of vaginal hygiene – keep the area clean. Regular baths or showers will help you feel fresh and clean. Do not use harsh soaps on the genital area. Use a fragrance-free soap or body wash;

red check mark very small  If you are fed up of brown discharge, never attempt to remove the IUD by yourself. Better visit your doctor for advice.


  1. I have brown discharge I have been on the mirena for about 4 months it doesn’t smell or anything and I just git off my menstrual 2 weeks ago. Is this normal???

    • it is mirena side effect

  2. I have the mirena since aug 2013 and i have a dark brown almost black discharge! M breast are sore and their is coming white stuff out! What can be wrong?

    • check pregnancy

  3. How can.I get rid off discharge odor ?

  4. I have a black coloured discharge and bad cramps been on mirena 6months now never had this before is this normal?

    • it is side effect from mirena

  5. I have dark brown/ black discharge and bad cramps..also blood clots. I got the mirena put in on 6/12/15. Do you think it shifted?

    • mirena has hormonal component which can trigger brown discharge; cramps are provoked by IUD (it is temporary); your body is adapting to mirena

  6. I had my Mirena out 4 days ago and experiencing brown discharge with little ‘bits’ in it. I’ve never had this during the time my Mirena was in place. What could this be.

    • just adaptation after mirena (hormonal component of mirena disappeared and body is adapting)

  7. I’ve had the iud in for about two months now. I didn’t have any brown discharge at first. My husband and I had sex with no problems except for one time. It hurt a little bit. It kind of felt like he pushed it in further. Ever since that happened I’ve had the brown discharge. No pain but that was about five out six weeks ago.

    • actually during sex you had mechanical push of IUD, it moved and scratched endometrium and you had brown discharge; with time you will discover the best safe position for sex

  8. So i’ve had my mirena (5years) for about 6-7 months now and i just had sex recently and it was pretty rough, so now its been 2 days since the brown discharge is leakin black discharge… Im getting worried. And also im cramping and my breast feel sore .

    • you are experiencing mirena side effects (cramping, breast sore) and post-traumatic brown discharge

  9. I had my iud placed in jan 2015 after my 4th child i have a purple brown mucas discharge since is that normal?

    • if it happened only once, it is OK but if it is on-going, better to visit your gynecologist

  10. I had mirena inserted about 7 months ago. I initially bled for about 5 weeks post-insertion. I haven’t bled since. Niw I am all of a sudden on day 4 of brown spotting. No odor. What’s going on?

    • it is mirena side effect

  11. I had mirena placed about two weeks ago. I only bled for two days following. The last couple of days I’ve had a tan colored mucus coming out. I had a post insertion ultra sound a week after it was placed and the dr said it looked really good. The cramps are so severe I have to stop everything I’m doing and lay down. Is this normal or should I call my dr?

    • during first month your body will be adapting but if it will be longer, better to speak with your doctor

  12. I have had Mirena for a year now, and when i have my period, it is only dark brown blood almost black. Very rarely do i get red blood. Also lately i have been experiencing cramping in my right lower stomach, not horrible cramping, but it isnt comfortable…

    • it could be mirena side effect

  13. I’ve been on mirena one year
    3 bv infection s one yeast
    Since bv has cleared up
    Brown discharge looked like it was combined with monistat cream
    Got ph balenced now brown discharge looks like dried blood too
    Cramping last week

    • many women with IUD have vaginal infection because microbes easily “clime” up; brown discharge is a typical side effect of mirena

  14. I had mine inserted in may 2015, my last period was on the 12th of july 2015 and has be regular. This month I only had brown discharge and when I wipe I get red spotting at times. 2 days ago, I wipe and had a clear white discharge with red stains. I had intercourse on 21 july, could it be implantation bleeding or is it just me. I took a pregnancy test today and it was negative. I have been feeling tired lately, nauseous, headaches and chilled when its hot outside. I am yet to receive my heavy period I have been receiving since on the IUD

    • it is not normal – visit your gynecologist

  15. I have had my mirena since March. I got it once in February but it fell out so I got this new one in March. I randomly get cramps, weight gain (like 20lbs) And I always get clear and sometime brown discharge, it’s actually getting annoying. Headaches occur more often as well. Went to neurologist and they couldn’t find anything. Any thoughts?

    • mirena has hormonal component – Mirena (levonorgestrel-releasing intrauterine system)- Mirena releases small amounts of hormone directly into the uterus – you could have side effects because of levonorgestrel

  16. Hiya iv been on the mirena 3 years and my last period was brown blood then got a little bit of pink with gung and then finish off brown I had no pain at all I’m my stomach I just had real bad pains in ma boobs what’s goin on plz help

    • Mirena is a hormone-releasing intrauterine system – it is slowly and permanently is releasing hormone levonorgestrel in your uterus and you are experiencing side effects from this hormone (brown discharge, breast tenderness, etc.)

  17. Have had mirena iud a little over a month. About a week ago started having a sometimes clear sometimes brownish discharge. It doesn’t have an odor. Went to the doctor because I thought it was a yeast infection but it wasn’t. This is getting annoying. Is it common?

    • common mirena side effect

  18. I’ve had my mirena for 2 years now and have always had a very light and short (1-2days) period each month like clockwork. In June this year (and the months following) my period stopped being as noticeable — just a little red/brown discharge for a day that hardly needed a tampon/pad. I noticed a small amount of brown discharge in June between my period (which had never happened in my life), but it went away pretty quickly so I ignored it. Now, in August, I have had some light brown discharge for 3 days and then today it was black. All very very small amounts, but alarming just the same. Any idea what could be the cause?

    • could be mirena side effect

  19. I got my IUD on July 11th 2015 (Mirena). I switched from my pills (Ortho Tricyclen Lo). I have experienced sharp cramping on either side of my uterus not as a whole. I have been bleeding ever since i got it in. I have read that brown discharge can come from having sex often on Mirena. I have also read that soreness is common after intercourse? Today i had a lot more than usual but my partner and I had sex anyway. He has told me that he can feel the strings but last night he said that he could feel something else. He told me that usually he doesn’t go that deep and when he did he said it felt like something that wasn’t me. My main question here is, is the large to small amounts of brown discharge normal? As well as, if my Mirena is coming out would it be very obvious and happen almost all at once or is it possible the end is sticking out. The idea of a man made device inside of me scares me and I am terrified that I could get pregnant. Please ease my mind here.

    Thank you,


    • 1). brown discharge is common for mirena because mirena has hormonal component; you can request IUD without any hormonal component;
      2). sometimes IUD can move – better to check with your gynecologist and be sure
