Postpartum help

Jessica

I'm probably going to get a lot of hate for this. We had our daughter back in July of 2019. My first period after having her was last week. Lasted six days. Was pretty normal. Little heavy bleeding. Severe cramps. Then it ended. Here I am a few days later and I'm bleeding AGAIN. There was like a five day interval. Is this normal? Could I possibly be having a miscarriage? I'm on the pill, but it's not always consistant due to a very active lifestyle with work.
