Is it normal to have a 2 day period during the placebo week of taking a pill? (The week where there is no active pills) I normally have 5 with light brown but this “period” it seemed to only last 2 days?

Today was very very VERY light brown, almost normal. But I’m not counting it due to it looking practically normal.

Is this normal? Last “period” was extremely wonky due to me taking an antibiotic. I had a 2 periods in the same month.
