Postpartum period lasting longer than 7 days

I just got glow this past week, and I’m charting my first period after having my baby. I bled for more than 7 days, and it won’t count the extra days as my period. It’s very light but it’s still there. Is there a way to extend it? I can’t figure out how. All I can do is say I’m spotting but it says it’s ovulation spotting. Maybe that’s the case but I think it’s just a bad first period.
