I understand your concern, but I'd say it's extremely unlikely you contracted the virus. The easiest way to know for sure is a simple blood test. Studies have been done where couples had been together for 20 years or more, one infected with HCV and one not, and had unprotected sex. The person who was not infected never caught it from the person who did have HCV. So you're pretty safe, not guaranteed, but pretty safe.
Right, I know its not it just the part that blood was involved
hep c is not an std. too much information for me.
