My fiancé has felt weak, had a fever off and on, pains like heartburn, can't sleep at all, coughs non stop, and is throwing up a lot more lately. We need advice on what to do, we have no medical insurance. So we hate to make a trip to the hospital for nothing.

There's really no way for anyone on the internet to give you a medical diagnosis. No one can. Not even a doctor.

It's time to find a way to get your fiancé to the doctor. The symptoms you're describing should not be left untreated.

Good luck.

For nothing??
Your title says black specks, but you don't elaborate.
I'm guessing 'coffee grounds' vomiting, which means that small bits of blood have turned black in the stomach. Be sure to say that to the ER.
