Cons of IUD
Must Be Inserted and Removed by a Physician
Insertion and removal of an IUD must be performed by a physician. A medical evaluation is necessary to assess the suitability of the individual’s body and the position of the uterus before the procedure.
This helps ensure that the insertion is safe and effective.
A Pelvic Examination Is Required Before Insertion
Before inserting an IUD, the physician will perform a pelvic examination to assess the readiness and position of the uterus. This also helps screen for conditions that may be unsuitable, such as pregnancy or infection, in order to prevent possible complications.
Mild Discomfort May Occur During Insertion and Removal
During insertion or removal of the IUD, you may experience mild pain or cramping similar to menstrual cramps. Slight spotting or light bleeding may also occur. These symptoms usually improve on their own within a short period of time.
Menstrual Changes May Occur 🩸
- Copper IUD: May cause heavier or longer periods, especially during the first few months.
- Hormonal IUD: Usually results in lighter periods, and in some cases, menstruation may stop altogether.
Individual responses may vary.

After IUD insertion, there is a slight risk of developing pelvic inflammatory disease (PID), most commonly during the initial period after insertion. The risk can be minimized through proper pre-insertion screening and appropriate medical care.
In very rare cases,
uterine perforation may occur. This is an uncommon complication, and the physician will assess the risk and monitor symptoms closely.

IUD Expulsion: This can occasionally occur, most commonly within the first year after insertion, with the risk decreasing in subsequent years. If you notice anything unusual, you should see a doctor for evaluation.
-
Malposition: An improperly positioned IUD may reduce contraceptive effectiveness. This can be detected during follow-up examinations with your doctor.

Unable to Feel the IUD Strings: Not being able to feel the strings may make removal more difficult. Regular follow-up visits are recommended to ensure the IUD remains in the correct position.

IUD Breakage (Very Rare): In rare cases, the IUD may break. If you experience unusual symptoms such as severe abdominal pain, seek medical attention promptly.
