The three month period is enough. None of the symptoms you describe sound related to herpes. We don’t know if repeated negatives are any more reliable in terms of missing infections than one negative. With HSV 1, I know that repeated testing does not help pick up more HSV 1 infections in an individual. I think it’s great that the sex worker reached out to you to reassure you about this. I think you should move on with a negative IgG at 12 weeks out.
