Ugh, I'm so sorry.
I can't give you odds on this. Getting a false positive on an IgG once means you are likely to do so again, but it's hard to say if this is a false positive since the WB was indeterminate.
Terri Warren is a nurse practitioner who is one of the leading experts in herpes. She offers consultations and can work with you to get another WB test. The downside is that you have to self-pay.
You can start by talking to her here - https://westoverheights.com/herpes-questions/ It's $20.
If you want to go right for the WB, it's here - https://westoverheights.com/herpes/getting-a-western-blot/
If I were you, I'd start with the question, and go from there. I can totally vouch for her - she's been a part of loads of groundbreaking herpes research, and she had a clinic for many years. I've heard her speak, and have met her. (I also get nothing, financial or otherwise, from recommending her.)
Terri and many other experts feel that anything below a 3.5 needs to be confirmed, so there is still a chance that your tests are false positives.
Please let me know what happens.
