I stopped bleeding completely around 5 weeks postpartum, but now at 6 weeks postpartum I now have heavier “spotting” and it’s bright red. The reason I’m questioning if it’s my first period or not is because

1. It’s really light (like 1 pantyliner will last the whole day)

2. I don’t have any of my normal period symptoms

Is this my period starting back or just a weird comeback of postpartum bleeding?

Side note: I’ve been on the mini pill for a month now.
