7 weeks post csection period?

Shalee

I stopped bleeding about 5 weeks and I went to my 6 week and Dr checked me all out and looked inside and said I was good. But now at just over 7 weeks I've been bleeding of and on since Sunday..OB suggested it could be period and it can be very irregular since I am breastfeeding.. after not bleeding for so long everyone it starts again I get anxious and worried something is wrong, ob did not seem concerned whatsoever. What's everyone's first Postpartum period experience?
