I was infected with hep c for 37 years. I was probably infected in 1977 and found out I was in 1990. I treated with what was available at the time on three severer attempts as new treatments became available but with no luck. The old treatments were only about 30% effective for those with genotype 1a hep c which was the most common ant the type I had.
In 2008 I was diagnosed with liver cirrhosis. About 20% of patients who have hep c for 20 years will develop cirrhosis. In 2008 I was likely infected for 30 years.
In 2014 the new generation meds started being approved. New medicines are highly effective and much better tolerated than the treatments that I experience back in the day. I was finally cured of hep C in 2015.
Hepatitis C he’s a very slow acting illness it takes decades if ever to cause serious liver damage but it can which is why it’s important to treat.
Long story short and to answer your question, you’ve had hep c for a very long time a couple of months won’t make any difference even if you have liver damage now. But the sooner you do get treated you won’t have to worry about carrying a blood borne illness that you could potentially give to others. The important thing is to not share personal items that could have blood on them like fingernail clippers, razors or toothbrushes. Household transmission is rare. It is safe to share drinking glasses and eating utensils. It is safe to kiss your loved ones. For long-term monogamous couples it is very rare to practically nonexistent for transmission to occur. There are many examples of long-term married couples were one has hepatitis C and the other does not.
Best of luck
