Is there something that i can do?

Good morning I'm on maternity leave and my manager said I have to pay for my health insurance while I'm out. I've never paid for health insurance. My insurance has been terminated because I can't afford the premiums. Is there anything that can be done. Is there someone I can call to see if this is correct. Last time I went on maternity leave I didn't pay health insurance I only paid my portion for dental.
