you didn't mention for what reason you have had your uterus removed.
bleeding following subtotal hysterectomy
is unusal. this type of bleeding may be due to chronic cervitis or intra epithelial cervical dysplasia
.So, have a paps smear and cervical biopsy
to exclude potentially malignant stump lesion.If both test have negative results for cancer,consider chronic cervicitis
,have a course of antibiotic and laser or cryo ablation of cervix.
