There is no connection between your hernia
and vaginal bleeding. Hernia is anatomical defect of your abdominal wall which should be operated with reconstruction. The cause of bleeding is, to my mind, a possible resection of ovary with which was done during previous operation (it happens quite often when a surgeon has to remove adhesions and reconstruct normal pelvic anatomy). You also had policystic ovaries so I consider that it was a drilling or resection of ovaries. Hormonal
function of ovaries after operation was slightly damaged. It can be corrected prescribing oral contraceptives for some time and after that they will work properly.
Wish you Good Health
