If you still are bleeding, go see a doctor. ER or urgent care, if the bleeding is severe.
If you are not, go call your doc on Monday, explain that you think you have a tear in your vagina. You don't have to be more explanatory than that with the receptionist, but you do need to explain to the doctor. I know it will be embarrassing, but you should get seen just to be sure of what caused the bleeding. (ps -- Doctors have seen worse. At least the carrot is not stuck in your behind and won't come out, like my sister had to deal with once when she was an EMT.)
