Exercising after c-section

Wanted to ask to all those moms who had a c-section... I had mine done a 7weeks ago and two days ago I started walking and jogging for 30sec and resting for like 40-60sec and doing it again, the thing is, I felt great, didn’t feel any discomfort or pain on the area but suddenly the day after and today I’ve been bleeding. I’m breastfeeding FT so I barely had my period (at least that’s what I noticed). I don’t have any pain or little discomfort but nothing serious for my pain tolerance.

Could I be bleeding because it’s the period or because I did too much for been only 7 weeks?
