C-section/period???

I had my C-section on December 14, 2018 and I've been bleeding but the bleeding would stop then start back up but i would only spot and it was mixed with mucus towards 4 weeks pp well about 2 days ago I thought I was done bleeding then I started to bleed heavier and bright red with some clotting.. How can you determine if the bleeding is from the C-section or if I've started my period?? especially since there hasn't been time in between. I'm also exclusively breastfeeding of that makes a difference.
