Transaction confirmation

today something very strange happened I would like to know how I can track a transaction of my account I do not know if I was hacked or was a legitimate transaction, I entered my open with metamask, and suddenly I asked for a confirmation and when I accepted it I practically withdrew my funds I can not find the origin what can I do?
