Hi, LostinSpace, and welcome to the forum! It appears that you are one of the lucky ones whose immune system fought off your acute hep C infection. I believes that happens within 6 mos. of the exposure. Since you've had quite a bit of testing and have the antibody for hep C, you really have nothing to worry about. You cannot get it again nor can you pass it on. This happened with me with hep B but not C. I developed chronic active hep C (CAHC.)
If you are able to pinpoint when you contracted the virus, and if your children were not born during that infectious 6-month period, I believe they are okay, too. If you want to give yourself reassurance, you could have them tested, too. It's very rare for HCV to be transmitted sexually. This is a blood-borne disease.
It takes decades for symptoms to first appear in one who has chronic active hep C. The most common symptom is fatigue and elevated liver enzymes. If left untreated (or if unresponsive to treatment), it can progress to cirrhosis and liver cancer.
I hope this answers your questions.
