Fever and zero appetite

hey all, I've had a fever the past few days and have had zero appetite during this, I forced myself to eat a couple of times a day but I still didn't consume enough calories. To be honest I was probably sleeping 18 hours out of the day because the fever just stole my energy away and I couldn't do anything else. Anyways, I really hope it's not going to hinder my progress but when I clicked complete entry for the day, the app said they weren't going to count anything I ate for the day towards anything. I understand wanting to discourage consuming an extremely low amount of calories because it's highly unhealthy. But I was just sick and didn't want to eat. Is there any way I can modify my entries so the people who work for my fitness pal can make the past two days count?
