Until you know for sure that your girlfriend is infected with hepatitis C why worry? Until your girlfriend is known to have a chronic hepatitis C infection you are worrying about something that doesn't exist.
Secondly hepatitis C is not a sexually transmitted virus. It is a blood to blood virus the is most efficiently transmitted through IV drug use.
CDC
How is Hepatitis C spread?
"Hepatitis C is usually spread when blood from a person infected with the Hepatitis C virus enters the body of someone who is not infected. Today, most people become infected with the Hepatitis C virus by sharing needles or other equipment to inject drugs. Before 1992, when widespread screening of the blood supply began in the United States, Hepatitis C was also commonly spread through blood transfusions and organ transplants.
People can become infected with the Hepatitis C virus during such activities as
Sharing needles, syringes, or other equipment to inject drugs
Needlestick injuries in health care settings
Being born to a mother who has Hepatitis C"
What are ways Hepatitis C is not spread?
"Hepatitis C virus is not spread by sharing eating utensils, breastfeeding, hugging, kissing, holding hands, coughing, or sneezing. It is also not spread through food or water."

Thank you! I'm so afraid of contracting this.
Doubtful, but wait a few months and have yourself tested for antibodies just to set your mind at ease.
