Do copper IUD cause heavy, painful periods and cramps?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I got a copper IUD inserted six months ago after my second baby. Since then, my periods have become heavier and more painful. Sometimes I feel cramping even in the middle of my cycle. Is this normal, or could the IUD have shifted? I am also wondering if it can affect fertility long-term.

I might want a third baby in a couple of years. Please help me understand what is normal and what is not. Will having an IUD now affect my fertility later? Is a hormonal IUD better for women with PCOS or heavy bleeding?

Please advise.

Hi,

Welcome to iCliniq.com

I read your query and understand your concern.

The complaints that you have are the complications of the copper intrauterine contraceptive device (IUCD), spontaneous expulsion, misplacement of the IUCD, heavy menstrual bleeding, painful menstrual bleeding, and no protection against sexually transmitted diseases (STDs).

I recommend that you shift to Mirena. The best option for you is Mirena.

Mirena is a hormonal intrauterine device (IUD) used for birth control and heavy menstrual bleeding. It is a T-shaped plastic device that releases the hormone Levonorgestrel into the uterus, preventing pregnancy and potentially reducing bleeding.

Mirena can be used for up to eight years for birth control and up to five years for managing heavy bleeding. It contains Levonorgestrel-releasing intrauterine system (LNG-IUS) 52 mg and releases a daily dose of 20 μg per day into the uterine cavity.

Mirena provides an effective contraceptive with shorter, less painful periods.

  1. Jaydess is a new LNG-IUS which contains 13.5 mg and releases 6 to 10 μg every day.

  2. Kyleena contains 19.5 mg LNG-IUS, which is released at the rate of 17.5 μg per day.

  3. Liletta releases daily of 18.6 μg.

Mechanism of action: Thickening of cervical mucus inhibits fertilization and ovulation, preventing endometrial growth and causing endometrial atrophy.

Indication:

  • Contraception for five years.

  • Heavy menstrual bleeding.

  • Dysmenorrhea.

  • Premenstrual syndrome (PMS).

Contraindication:

  • Known or suspected pregnancy.

  • Current or recurrent pelvic inflammatory disease (PID).

  • Lower genital tract infection.

  • Cervicitis.

  • Endometritis.

  • Cervical polyp.

  • Cervical cancer.

  • Endometrial cancer.

I would recommend that you use Mirena. Consult your specialist doctor, discuss with him or her, and take the medicines with their consent.

Hope this answers your query.

Thank you.
