Do you think they'll fire me?

So my fiance had our baby girl on the 12th, which I wasn't scheduled to work the 12th or 13th. However my baby was born with complications and we have constant Dr. appointments to check her jaundice levels, appointments with a pediatric cardiologist as she was born with a heart condition. So far I've missed the 14th and 15th shifts and it looks like I'm going to have to miss this one too but I'm worried about getting fired. I'm a part time grill cook that has been there about 3 months now so I know I'm not entitled to any kind of leave but I don't know what to do.

Any thoughts on what I should do or if you think I'll get fired
