text: do you have hepatitis c? if you are a person with hepatitis c...please tell me everything to do with hepatitis.  how long it takes to show up in blood work, can you have kids, if having sex on your period is a high chance because i heard that it wasn't, and everything else please. i cleared it on the treatment (interferon & ribavirin) 6 years ago. it can take a few months to show up, but you have to be specifically tested for it. i have 2 children, neither one has hep c. there is a <8% chance of passing it to your children and a <5% chance of becoming infected through sex. there is way too much information to tell you everything about it. my advice would be to treat it as soon as possible; why wait until you have more liver damage. the chances of clearing it are better the younger you are.  get vaccinated against other forms of hepatitis (a &b).  educate yourself by joining a good support group.  don't drink alcohol (that should be the #1 advice!). best wishes to you.
