Fiance lost job while I'm 38 weeks pregnant

My fiance works 2 jobs that barely cover the bills. He got let go from the job that pays the majority of the bills.

We get food stamps but I go many days not able to eat because the fridge is empty regardless of what budgeting and meal planning I do.

My midwife says get protein powder because I don't eat enough but I can't afford it.

I'm terrified that we won't make it financially and I can't do anything because I could give birth at anytime now.

I've been listing anything I have to possibly sell online but no traction.

Any advice? I need help ASAP
