6 weeks after csection... period?

☆Amber☆ • Wife, daughter, sister, and mother of 4! this pictureis 2 weeks after.my c section!
I had my baby 6 weeks ago via csection, and bled for like 3 weeks, then it started just coming and going depending on activity level. Well .. this morning it's like I just gave birth lol, it's pretty heavy but not heavy eno ugh to go to the dr , but it's crazy! My back is all crampy too.. I used to have the lightest periods ever, but could this be my period or should I be worried? I had to miss my check up, and have it rescheduled for next week...
