Can withdrawal bleeding be scant?

Good morning, I take Vibin contraception, but I am now in a break for bleeding (4 days) and today at 10 I started bleeding, but it was different than usual, I always bled very much, and today after ingestion I as if it disappeared, bleeding is very scant, a week ago I was cold, but I did not take any drugs that interfere with contraception, until today I had a stressful day, or by stress or generally with bleeding during withdrawal can be scant bleeding? I'm taking Vibin from July 2020. Please reply
