Still bleeding

Its been almost 10 weeks since i had my c-section, and im still bleeding everyday. My ob messed up and cant get me in for a post partum appointment until april 20th. Ive gotten to the point im always tired, my body hurts, i have daily head aches. And its not because im sleep deprived my little one is still in the nicu with some issues. Is this normal? Should i be concerned at this point?
