Only one day — Day1 and Night1 — only period, I only use 2 napkins. Is that normal?

Day 2 there was little to no blood at all only a hint on my napkin like one teaspoon then Night2 none just a hint also

at NIGHT I don’t have blood on my napkin and today day3 no period at all

Is that normal? Btw I am stressed and also started doing intense workouts, is that the side effect?

Thanks
