Not immune to Varicella

My bloodwork came back ok, except I'm not immune to varicella (chickenpox/shingles). This is my second pregnancy and wasn't and issue during my first. If my first pregnancy blood work came back immune and this second pregnancy blood work came back not immune, that's weird right? Is it more likely to be a false negative or a false positive? I have 100 questions for my doctor at my next visit but I was just wondering if anyone experienced anything similar.

I read some information on the CDC website which concerned me. My due date is June 1 and the highest number of cases are between March and May. The risk for pregnant women is highest 5 days before and 2 days after delivery which could result in an infant mortality rate up to 30%.

I'm a cookie-cutter product of vaccine scheduling and I did have the chicken pox as a kid. How could this just be an issue now?
