Facebook ads minimum bid?

[Urban]

Lets say that my suggested minimum bid for CPM is 0.35$ and I set mine at 0.04. Does that mean that my ad will be shown with way lower frequency or it means that it will not be shown at all because it's bellow suggested minimum bid?
thanks a lot

I might not be clear enough with my question. I want to know if FB could stop showing your ad all together because the bid is too low. I don't care if the frequency goes down, as long as they still show it, like lets say 10 times a day, which is super low, but at least they still show it.
