So I am asking for my sister.. she delivered her son via csection on September 13th. Two weeks after delivery she had sex (unprotected with her bf finishing in her) She told me this morning that she had sex 3 days ago and now has started experiencing very heavy bleeding. I’ve already told her even with a c section it’s recommended to wait the 6 weeks! So does this sound like something that could be serious or maybe normal? The bleeding is from her vagina not from her incision.
