Sinus infection at 15 weeks

Sunday, I woke up with the worst cold. I’m use to colds turning into sinus infections but this is taking everything out of me. I’m normally feeling back to myself in a couple days and here it is FRIDAY and I feel like every oz of energy has been sucked out of me. My doctor gave me some antibiotics a few days ago but I’m still exhausted, lightheaded, and nauseous. Does anyone have any advice on how I can get some energy to at least get the dishes clean and put up and basic cleaning done ✅🤒🤒🤒
