Hello! I am 5 months postpartum with my second child...both deliveries were c section. 2 weeks after delivery I went back into surgery to remove a seroma that was causing pain. The next day, I was admitted and spent 2 weeks in the hospital with HA-MRSA. My son is exclusively breastfed; however. My period returned January 2nd. I bled for 9 days, very heavy. My period returned again on January 22nd for 4 days. Since stopping, I bleed randomly (red blood) and nearly every time I use the restroom I have black, thick and stringy blood. I often find some in my underwear also. Is this normal?
