Work and bleeding

Sarah • I have two beautiful children a boy and a girl. TTC baby #3
I started back to work at 5 weeks post partum, a few days later I started lightly bleeding. About a week or a week and a half started bleeding heavier and darker. But not enough to soak a pad in an hour. I'm still bleeding now at 7 weeks post partum. I couldn't make my 6 week post partum check up due to work and so I rescheduled it for Feb 29. But just wondering if bleeding this much is normal? I only am working 5 hours shifts 4-5 days a week.
