In my opinion chance of HCV extremely low if any at all.
Just like the expert doctor told you regarding HIV. "The risk of other STDs is higher, but still low"
"But of course you can consider testing if you would like the reassurance of negative test result".

I suggest you look here

and check the health department guidelines in your country.
Best of luck. Getting knowledge about, likely exposure risk situations,, practicing the guidelines for prevention and getting tested if still in doubt for reinsurance about hepatitis, HIV and STD's.
It is understandable the those who are mostly unaware of the specifics to get quite alarmed when encountering a possible exposure situation.
I'm not referring to you. But some people who after learning and even getting tested to confirm they have not caught anything still persist with doubts and anxiety It can be similar to a fear of flying, driving or other low risk activity that may need a consultation with a mental health professional if it's an ongoing continuing fear lasting more than a few months.
I wish you the best.
