Hpv diagnosis

Okay, so in December I was diagnosed with HPV. It was at my first OB appointment with the pregnancy.

I was brought back and tested for lesions and all that to which none were found. My doctor told me to watch for warts and I have been.

I haven't found any.

Is it possible the results were a false positive because I'm pregnant??

Or do some people have it but don't develop warts??
