Possible infection?? Or normal

Hey guys so I have an appointment tomorrow to see my doctor but just wanted to come on here until then. Anyways, I had a c section 8 weeks ago but I keep off an on bleeding. My time frame is like this.

-Bled 4 weeks straight

-week 5 : no bleeding

-week 6: heavy bleeding

-week 7: no bleeding

-week 8 heavy bleeding

Is this normal? By no bleeding I mean no bleeding at all not even 1 drop.

I am breastfeeding and my periods before this pregnancy we’re very regular. Even after having my first baby 2 years ago.
