Very short period?

Zoe • Married 01/08/15 👰🏽Miss T born 03/06/16👧🏽 Little roo due 06/04/20 👶🏽

My periods normally last 5 days but this time it started on the expected date but I only had 2 very heavy days & the third very light & today would be my 4th but there's nothing has anyone else had this? Since having my daughter ² years ago they've been very consistent & I've never had a period last less than 5 ever. Has anyone else experienced this before?
