Super Short Periods on the Pill

Hello, I had a baby girl in December and started back on the pill the first week of February. The first two periods I had was my normal 4-5 day bleeding. Ever since then for the past couple months my period has only been two days. I spot for a day or two before then bleed for a day or two then spot until there's nothing left or until I start the new pack the following week. Is this normal? I've never in my life had such short periods (definitely not complaining) and it's just not normal for me at all 🤔
