How long after IUD insertion can you insert anything?

I got my IUD on Wednesday and my doctor never told me anything about not inserting anything but I’ve always read you aren’t supposed to. I have vaginismus so I use dilators to help and I was wondering when I can start using them again. How long after IUD insertion can you insert a finger or dilator?

Edit: thanks for all the answers! I just have a fear of messing it up haha so I’m just giving it some time I guess. I think I’ll feel more comfortable after a week has passed thank you!!
