My cat thinks I'm pregnant

Emily • Pregnant with #1!!!!
This might be weird and I might be completely wrong, but I read that animals can tell when you're pregnant because of the hormones you put out. This being said, my cat used to hide all day but now as soon as I walk into the room she is by my side. As soon as I sit down she is in my lap kneading my stomach. This has been going on for a week and it's still too early to test and I'm not having symptoms, but it makes me think.. Am  I pregnant or does my cat just love me?? (I'm aware that this sounds crazy)
