Am I an awful person?

Today my husband and I went by PetSmart to look for a dog runner and obviously I saw kittens and took my daughter over to look. Well I ended up falling in love with one that was by himself he was super fiesty and sweet I was super excited about it and was supposed to come back the next day to get him. But now I've been tossing and turning all not thinking about how I'm not ready for another cat but what if he never gets adopted? I just lost my cat of 15 years less then a month ago and my other cat of 8 years two months ago and I'm pregnant, have a toddler and two dogs I just don't know I can mentally take on another animal right now. I just don't know what to do...
