Thanks for the query.
Some amount of irregular spotting can be seen with IUCDs.
And women with IUCD are more prone for infections.
So, better to consult gynecologist once and get examined.
once to check the intra uterine position of the IUCD and to rule out any pelvic infection
In case of pelvic infection you may need one course of antibiotics.
After ruling out the pelvic infection, you can continue with symptomatic treatment.
If the symptoms persist or become severe, you may need to get remove the IUCD.
And can continue with non hormonal
contraceptives like barrier methods
, physiological methods etc.
