Missed misscarriage

Jess

I'm not sure where to post this, but I've been trying to search online and haven't found something....

I was told Thursday 6/20 that I have a missed miscarriage, I should have been 13weeks+4days ....I measured 8weeks+4days.

Well how long should I wait to see if I can pass this on my own? Is it bad to carry the baby dead? I have no cramps or any feeling of anything coming or bleeding or spotting.
