Some women may experience heavier, longer periods and spotting between periods can occur – normally for up to 2-3 months. However, if your periods continue to be heavy or long, or spotting continues, contact your healthcare provider.
Infrequently, serious side effects may occur:
• Pelvic inflammatory disease (PID): Uncommonly, IUDs as well as the IUB are associated with PID. PID is an infection of the uterus, tubes, and nearby organs. PID is most likely to occur in the first 20 days after placement. Contact your healthcare provider right away if you have any of the signs of PID: abdominal or pelvic pain, painful sex, unusual or bad smelling vaginal discharge, chills, heavy bleeding, or fever.
• Difficult removals: Occasionally the IUB may be hard to remove because it is lodged in the womb.
• Rarely, the IUB goes through the wall of the uterus, especially during placement. This is called perforation. There is an increased risk of perforation if you are breastfeeding or recently given birth within 36 weeks before insertion. In this case you are not protected from pregnancy and the IUB will need to be removed.
• The IUB may partially or completely fall out of the uterus. This is called expulsion. Women who have never been pregnant may be more likely to expel the IUB than women who have been pregnant before. If you think that the IUB has partly or completely fallen out, use an additional contraception method, such as a condoms and contact your healthcare provider.
