Bleeding After Intercourse

Hello there! I had my C Section exactly 2 months from now,(12August 2016) my wound got worst with infection in it, which recoverd after heavy antibiotics and injections and had been bleeding since then, which stopped last week. I had an intercourse and started bleeding again heavily. Is it normal? I am a breastfeeding mom and getting weak due to this, help me!
