There are no contraindications to wearing a cup with an IUD.
IUDs are contraceptive methods that are placed in the uterus, while the cup must be placed in the vagina.
There are, however, some precautions to take:
Ask your gynecologist or midwife for advice and do a little follow-up during the first few months to check that the IUD has not moved.
When inserting the IUD, ask your gynecologist or midwife to cut the strings of the IUD short. This will prevent you from pulling on them when you remove your cup.
Avoid pulling hard on the cup when removing it.
