Is it possible to fail a bulk? Feel like I’m just getting fatter.

So far I’ve gained around 6lbs and looking at pictures, I don’t look and more muscular at all. The body composition scales at my gym (which I use regularly) say I’ve gained slightly more muscle than fat but I’m not sure how much I should trust them. Also, I’ve gained a slight bit of strength but nothing to write home about. I’ve bulked before and it seemed like I just got fatter. I’m eating right, sleeping right, training right... feel like my body just doesn’t grow muscle well for some reason.
