Menstrual Period

I gave birth last nov 30 2018. After giving birth, i bleed until first week of january 2019 (OB said its normal). OB gave me Daphne pills since i was breastfeeding then i had my normal monthly period last week of january that lasted for 5 days. I stopped breastfeeding last week of January coz I have depression. I switched to Diane (pill), hanggang ngaun wala padin akonh monthly period. Is it normal mommies?
