Common Side Effects of Mirena IUD

01. Risk of Ectopic Pregnancy

Again, Mirena is a safe contraceptive. However, less than 1% of active Mirena users may experience unexpected pregnancy. If you get pregnant while using this device, there can be an increased risk of ectopic pregnancy.

Note that, Mirena users are generally at lower risk of being ectopic pregnant compared to other women with no contraceptive.

02. Mood Changes

Every woman has her own body chemistry, right? Therefore, few mood changes can be seen or unseen on Mirena users. Some women can experience an increase in anxiety and depression while using Mirena. You should track your mood for few months after inserting the device to avoid further complications.

03. Risk of Vaginosis

One of common Mirena side effects is vaginosis. Yes, all IUDs increase the risk of bacterial vaginosis. If you have a ‘fishy’ smell spreading out from the vaginal area, it may be bacterial vaginosis.

04. Changes in Cramping and Pelvic Pain

Severe cramping and pelvic pain are most common Mirena side effects. Cramps are typically seen within few days of Mirena insertion. However, as soon as your body adjusts to the device, cramps are reduced. As time passes, Mirena eases the cramping and pain significantly you have had during the periods.

05. Nausea Problems

All hormonal IUDs cause nausea. So you should be ready for a bit of nausea as one of Mirena side effects.

Because of Mirena uses, small ovarian cysts grow but the cysts don’t create further problems as they go away naturally. However, in rare cases, these cysts can cause severe pains, and you should go under surgery to weed out them.

07. Uneven Bleeding or Spotting

A few Mirena users can have some uneven bleeding or spotting. However, as soon as the body adjusts to the device, the difficulties should lessen. If the bleeding continues over 6 months, you should remove the IUD.

08. Stomach Upset

Women using hormonal IUD can have an upset belly. According to different studies, women who are with sensitive tummy should use Mirena like IUDs because of some extra facilities that come with these devices.

10. Lighter and Shorter Period
