I recently had a baby in June, 2013, and had an emergency c section. Shortly after was told im anemic i am having my first full blown period and its been on for 2 1/2 weeks now. At first it was old blood, and now for 10 days, i have been bleeding heavier and heavier, im now to the point im drowsy, very weak, and tingling in my hands and feet. Is this dangerous, if so, how soon should i see a doctor?
