am I a horrible wife?

So my hubby and I were set on not finding out gender. more him than me but I was okay with it because it's what he wanted. Saturday I was concerned because I had not felt baby move much over two days. Baby is usually super active and none of my usual tricks worked. I text to my doctor who told me I could go into labor and delivery to ease my mind. While there they did an ultrasound and I happened to see what we are having. I kind of feel guilty but at the same time it was not on purpose. Hubby still doesn't want to know, so I know and he doesn't. am I horrible?
