Sneak peek accuracy?

Rain

I took my sneak peek test at 14 weeks, I bleached my whole kitchen and no men were in there while I did the test and I sent it straight to the post office right after I got a girl result which I know is more accurate then a boy result I’m just nervous it could be wrong? What do you think? Should I share my registry? My doctor said the sneak peek has always been right for her patients
