On home rest and my job fired me

So I've gone above and beyond for this company over working and under paid handling and being the only person in my department. I'm 36wk with early labor I'm already high risk and notified my job Monday with doctors documents I need modified home rest to stop/prevent preterm labor. My job can be done from home. Had a conference call today and they fired me.

I have no idea what I'm going to do. I'm the only one with income. My husband is a disable vet and stay at home dad. I'm worried about my house my bills my family and my baby who I haven't had yet. What am I going to do. :(
