Question about iud and miscarriage

Sammy

Hey ladies, so I had a miscarriage back in July. I had an IUD placed in June. It was really difficult to reach my OBGYN due to Covid-19, when she called me back she told me as long as the tests I am taking daily are getting lighter and eventually turn to negative then we can assume a complete miscarriage. She didn’t want me to come in and pretty much rushed me off the phone 🤷🏻‍♀️

My question is; after getting pregnant and miscarrying is my IUD even still effective?
