Questions about copay

I have been having irregular contractions today. They're very painful, but not really a pattern. They feel very different than my BH.

Anyway, I called my doctor and they said to drink water and lay down for a couple of hours and they should go away.

They're not as painful, but still intense and still coming.

They said if they don't go away, then I should go to the hospital and get monitored and checked. Well, I can't really pay for a copay right now.

Do hospitals ask for a copay if you go to get monitored like that?

No rude comments please. I just don't want to go without money if I decide to go.
