I've been doing keto for a few weeks and I lost some weight, but I can't get my macros to add up. I reach my fats but not proteins or vice.

Macro percentages make no difference. Low carbs is all you need for ketosis and ketosis is all you need to get fat adapted.  Carbs and calories are limits, protein is a minimum ( you can eat more), and fat is for satiety and energy. If you feel good and satisfied don’t eat more to meet a macro.
