While hep c is not easily transmitted sexually for those who have multiple partners, engage in rough sexual practices where there is a risk of hep c infected blood entering the blood stream of an uninfected person, or in the presence of HIV there is an increased risk of transmission.
Wait 12 weeks and get tested for hep c antibodies. If that test is negative you are fine. If the hep c antibody test is positive the next step is to have the HCV RNA by PCR test. This test looks for the presence of the hep c virus in the blood. If there is no virus detected even though the antibody test result was positive this means you are not currently infected.
However if the HCV RNA test result shows detected and you have a viral load you will likely need treatment.
Fortunately the medicines approved since 2014 are much more effective than the old treatments with cure rates around 98% or better. Treatment now is very well tolerated by most people and can be for some as simple as one pill a day for as few as 8 weeks and you can be cured if you are infected.
Speak with your doctor, get tested, get treated if needed and get cured.
Best of luck to you
