Just wanted to tell my experience:
my fiancé filed the I-129 for me in October last year. We got our NOA2 in early March and I visited him for the last 2 weeks of March.never had any issues at immigration. They just asked me the usual questions. They didn’t me ruin the K1 neither did I. 
It was no different than any of my other visits to the US.
I was worried beforehand, but that was completely unnecessary.
