Menstrual cup and IUD?

Ke

When I got paragard placed, I was on my period and the doc said to use a pad for the rest of the week because my menstrual cup could accidentally pull the strings of the iud.

I don’t know if she meant I couldn’t wear it just after insertion or I can’t ever wear one.

Does anyone know if it’s safe to wear a menstrual cup with an iud?
