Hi,
Usually some amount of menstrual irregularities can be expected while using IUCD. And these will generally subside in early months. As the problem is persisting in your case, which is also leading to anemia, backache etc, better option is removal of IUCD after discussing with your doctor. If you want to continue, the possible risks are continuation of menstrual irregularities and
pelvic infection.
Before taking the decision of continuation you have to rule out local causes like pelvic infection with cervical erosion, which can present with spotting.
Pap smear to be taken. If test is normal, to control the irregular bleeding you can use anti fibrinolytic drugs like
tranexamic acid.
If problem still persists you may have to choose other methods like:
Hormonal contraceptives: Combined hormonal pills,
progesterone only pills, progesterone injection or progesterone containing IUCD (this is expensive compared with regular IUCD).
Barrier contraceptives like condoms etc.
Hope I have answered your question. Let me know if I can assist you further.
