Bleeding from gums when i do ablution (Wudu')

What should be done when bleeding comes during ablution? Should it be restarted? I have a situation in which when i do ablution my gums starts to bleed especially when i wash my face. Then i restart my ablution again and again from this state. I have a question that should i start the ablution again and again this situation? Or i can complete my ablution and clean my mouth at the end.
