Thermometer broke, no replacements

So, long story short, thermometer broke, friend checked stores around the area for a new one but there are none, I can't leave the house as am self-isolating, e-commerce can't get the thermometer shipped because everything not soap/hand sanitizer/masks has been deprioritized...

...so I can't monitor my temperature. I'm feeling better, but without a way to accurately check my temperature, I have no way of knowing if I'm fully recovered or not. Effing hell, do people not keep a thermometer with their first aid kit these days?
