Iud bleeding discharge

Hi everyone, well I’ve had my iud after having a baby back in June insertion happened in September, it’s been a year with the iud and right now I’m experiencing blood in my discharge and no where near my period. Anyone experienced something similar? I’m paranoid that it might of moved. My husband and I had sex four days ago and I was off my period for two weeks now… anyways after the act he said he had blood on him. I checked myself and yes I had blood but just as if your done with your period. It’s been four days and I’m still experiencing blood in my discharge should I be worried? I have doctors appointment on Saturday.
