I’m still testing from my possible exposure on oct 12, 2018. I’m still extremely nervous and scared. I went for my 5 month mark test with my doctor and the result was negative. They said it was conclusive but I’m scared because I keep hearing 6 months. One reference even said 12 months. I don’t want to be one of those individuals who get sick later on because a test didn’t pick it up. Will a test change from 20 to 24 weeks or the 6 month mark. Please help. I want all of this to go away. It was my first and last time ever having sex!!!! Please help
